A strong in-bed fuel tank for a pickup should match your fuel type, bed space, and refueling needs, while offering a capacity that suits your work. The Vigorighter 60-Gallon Combo stands out for pairing a 60-gallon aluminum tank with a 12 GPM pump and integrated toolbox. Other options include a 58-gallon low-profile diesel tank designed to fit under a tonneau cover, large-capacity RDS aluminum tanks, and simpler steel or aluminum models without a listed pump.
This roundup compares ten tanks using their stated capacity, material, dimensions, and included equipment. Before choosing, confirm bed dimensions, fuel compatibility, installation requirements, and whether you need a transfer pump or a tank intended to connect to the vehicle’s fuel system.
The Vigorighter 60-Gallon Combo is the best overall choice among these in-bed pickup fuel tanks because it combines a 60-gallon capacity, aluminum construction, a built-in 12 GPM pump, and integrated tool storage. It suits buyers who want a ready-to-transfer setup while preserving some bed organization. Choose the AM-TANK 58-Gallon Diesel if keeping a tonneau cover closed is the priority, or consider the RDS 69-Gallon Tank when maximum listed capacity matters more than having a pump included.

Detailed Reviews: Best In Bed Fuel Tanks For Pickups
#1 · Best Overall
1. Vigorighter 60-Gallon Combo
- Capacity: 60 gallons
- Material: Aluminum
- Weight: 85 lb
Best for: Fuel and tool-bed combo.
Why it ranks #1: Its 60-gallon aluminum tank includes a 12 GPM pump and integrated tool compartment, combining substantial capacity with useful transfer and storage features.
A built-in toolbox paired with a 60-gallon tank gives the Vigorighter a useful two-in-one role: carrying fuel while reserving a dedicated compartment for tools. Its included 12 GPM, 12V DC pump supports direct truck-bed transfers, making it a practical option for work sites that need both supplies close at hand.
The 31-by-19.88-by-9.5-inch storage compartment keeps tools within the same 50.2-by-19.88-by-24.8-inch overall unit, helping consolidate bed cargo rather than separating a toolbox and tank. The 12 GPM pump transfers fuel from the 60-gallon aluminum tank, and the listed fuels include gasoline and diesel. Corrosion-resistant aluminum is specified as a durability feature, while the 85-pound listed weight is relevant when planning loading and installation.
- 60-gallon capacity
- Built-in toolbox compartment
- 12 GPM 12V DC transfer pump
- Aluminum construction resists corrosion
- The listed 85-pound weight adds a substantial load before fuel is added.
Skip it if you need a lower-profile tank under a tonneau cover; AM-TANK 58 Diesel Pickup specifically lists that fit and includes a transfer unit.
This combo fits pickup owners carrying tools and gasoline or diesel for work-site transfers. Choose it when the 31-inch toolbox compartment is useful, and account for its 24.8-inch overall height and listed empty weight.

2. AM-TANK 58-Gallon Diesel
- Capacity: 58 gallons
- Material: Rotomoulded Antistatic Polyethylene
Best for: Tonneau-cover diesel transfer.
Why it ranks #2: The 58-gallon diesel tank is designed to fit under a tonneau cover and includes a 10.5 GPM 12V pump, hose, nozzle, and filter.
Its low-profile shape is specifically listed to fit beneath a tonneau cover, letting owners keep a diesel transfer station in the bed while closing the cover over it. The 58-gallon AM-TANK also includes a 12V pump, hose, and automatic shut-off nozzle for on-site refueling.
The 10.5 GPM pump and 13-foot dispensing hose support transfers to equipment such as tractors, excavators, generators, and trucks without moving the tank to the destination. The automatic shut-off nozzle helps stop dispensing at the nozzle, while the listed 30-minute duty cycle defines a boundary for sustained pumping. Its antistatic polyethylene construction and diesel-specific description suit buyers seeking a covered-bed diesel setup rather than a general-purpose gasoline tank.
- Low profile listed to fit under a tonneau cover
- 58-gallon diesel capacity
- 12V pump rated at 10.5 GPM
- 13-foot hose with automatic shut-off nozzle
- The pump has a listed 30-minute duty cycle.
Skip it if you need gasoline storage or uninterrupted pumping beyond 30 minutes; this tank is diesel-only and its pump has a stated duty cycle.
Pick this AM-TANK for diesel refueling when retaining tonneau-cover closure matters. Its 30-minute pump duty cycle is a real operating boundary, and buyers should plan transfers around that limit and the listed diesel-only use.

3. SWANGET 58-Gallon Diesel
- Capacity: 58 gallons
- Material: Polyethylene (PE)
Best for: Portable diesel job-site tank.
Why it ranks #3: This polyethylene diesel tank lists a 58-gallon maximum and a 52-gallon recommended safe fill, with a 12V pump rated at 10.6 GPM.
A 58-gallon maximum capacity paired with a stated 52-gallon safe fill gives this SWANGET a clear operating target for diesel transport. Its 12V transfer pump is rated at 10.6 GPM, and the polyethylene tank is described for truck beds, construction, farming, and remote refueling.
The stated safe fill level leaves room below the 58-gallon maximum for fuel expansion during transport, so owners should plan usable loads around 52 gallons rather than filling to maximum. The 10.6 GPM 12V pump supports powered diesel transfer at job sites, while the polyethylene construction keeps the listed tank material distinct from metal options. The product is specified for diesel only, making fuel selection a straightforward compatibility boundary for pickup owners.
- 58-gallon maximum capacity
- 52-gallon recommended safe fill level
- 12V transfer pump rated at 10.6 GPM
- Polyethylene construction for listed diesel use
- Recommended safe fill is 52 gallons, below the 58-gallon maximum.
Skip it if you need a 15-foot hose and 50-gallon diesel tank; Wolive’s Portable 50 Gallon Fuel Tank lists both details.
Choose SWANGET for diesel jobs where a portable tank and 10.6 GPM powered transfer are useful. Plan loads around the stated 52-gallon safe fill, not the 58-gallon maximum, for the specified transport guidance.

4. Vigorighter 51-Gallon Combo
- Capacity: 51 gallons
- Material: Aluminum
Best for: Tool storage with fuel transfer.
Why it ranks #4: Its 51-gallon aluminum tank pairs a built-in toolbox with a 12 GPM 12V pump, hose, and auto nozzle for a combined storage-and-transfer setup.
A built-in 31-by-19-by-8.8-inch toolbox lets this 51-gallon Vigorighter carry tools alongside fuel in one bed unit. The included 12 GPM, 12V DC pump, 13-foot hose, and automatic nozzle make it a transfer-ready combination for buyers moving gasoline, diesel, or kerosene to equipment.
The 50-by-19-by-21-inch overall footprint combines the fuel tank with a dedicated storage compartment, helping keep tools organized without allocating a separate bed area to a toolbox. Its 12 GPM pump and 13-foot hose provide the listed transfer setup, and the automatic nozzle supports dispensing at the destination. Aluminum construction is described as corrosion-resistant. During pumping and long-term storage, the supplied guidance says to open the pressure-relief valve to prevent vacuum collapse or deformation.
- 51-gallon tank capacity
- Integrated 31-by-19-by-8.8-inch toolbox
- 12 GPM 12V DC pump with 13-foot hose
- Automatic nozzle and listed gasoline, diesel, and kerosene use
- The pressure-relief valve must be opened during pumping and periodically during long-term storage.
Skip it if you want a tank without a stated pressure-relief maintenance step; Dee Zee DZ92556NB lists a venting coupler and drain plug instead.
Choose this Vigorighter when a toolbox, multiple listed fuel types, and powered transfer belong in the same pickup-bed unit. Keep the pressure-relief instruction in the operating routine, especially during pumping and extended storage.

5. RDS 69-Gallon Tank
- Capacity: 69 gallons
- Material: Aluminum
- Weight: 16 oz
Best for: High-capacity auxiliary fueling.
Why it ranks #5: The 69-gallon aluminum tank has the largest listed capacity here; RDS describes auxiliary fueling and diesel gravity feed, but no pump is listed.
The 69-gallon capacity is the defining advantage of this RDS aluminum tank, giving pickup owners substantial onboard fuel storage for longer workdays or remote jobs. Its 57-by-18-by-16-inch rectangular footprint provides concrete dimensions for planning bed space, while the product information describes auxiliary fueling and diesel gravity feed.
RDS says diesel can gravity-feed from the bottom of the tank, which can support a straightforward auxiliary-fueling setup without relying on a powered transfer pump for that feed method. For gasoline, the listed condition is different: it must be siphoned from the top using an electric fuel pump. The aluminum construction and 69-gallon capacity suit buyers prioritizing stored fuel volume, but the 57-inch length and 18-inch width make bed-space planning important before installation.
- 69-gallon fuel capacity
- Aluminum construction
- Diesel can gravity-feed from the bottom
- Gasoline auxiliary fueling is permitted with top siphoning by electric pump
- Gasoline auxiliary fueling requires an electric pump to siphon from the top.
Skip it if you need an included powered transfer setup; the listed gasoline method requires an electric pump, and this listing does not specify one as included.
Choose this RDS for a pickup needing a large 69-gallon reserve and a diesel gravity-feed option. Its 57-inch length and gasoline pumping condition are important boundaries for bed layout and fuel workflow.

6. Wolive 50-Gallon Diesel
- Capacity: 50 gallons
- Material: High Density Polyethylene (HDPE)
- Weight: 67 lb
Best for: Long-hose diesel transfer.
Why it ranks #6: This 50-gallon HDPE diesel tank includes a 12V electric transfer pump and 15-foot rubber hose, with a stated flow rate of 11.9 GPM.
The included 15-foot rubber hose gives this 50-gallon Wolive tank extra reach between a pickup-bed fuel supply and equipment. Its 12V electric pump is listed at an 11.9 GPM flow rate, while the high-density polyethylene body and solid lid support portable diesel storage and transport.
The 15-foot hose can extend the dispensing point away from the tank, and the 11.9 GPM pump provides powered diesel transfer from the 50-gallon capacity. High-density polyethylene is specified for the tank body, which the product describes as helping prevent leaking and deformation. The solid top lid helps keep rainwater from entering, according to the listing. Its stated use is diesel transportation, so buyers needing gasoline should select a different fuel-specific option.
- 50-gallon capacity
- 12V electric pump rated at 11.9 GPM
- 15-foot rubber hose
- High-density polyethylene body with solid lid
- The listed fuel application is diesel transportation only.
Skip it if you need gasoline transfer or a larger diesel reserve; Vigorighter’s 60 Gallon Aluminum Fuel Transfer Tank Toolbox Combo lists gasoline and diesel.
This Wolive suits diesel users who benefit from a long hose and powered transfer from a portable 50-gallon tank. Its stated diesel-only application is the central boundary, and the 20-inch width and 23-inch height inform storage planning.

7. RDS 45-Gallon Tank
- Capacity: 45 gallons
- Material: Aluminum
- Weight: 42 lb
Best for: Compact 45-gallon aluminum tank.
Why it ranks #7: The 45-gallon aluminum tank has fully welded seams and supports auxiliary fueling; the listed details do not include a transfer pump.
The 45-gallon capacity and aluminum construction make this RDS a more compact alternative within the brand’s auxiliary and transfer tank range. Its fully welded seams are identified as a durability feature, while the product also specifies a gasoline fueling method and diesel gravity-feed capability for distinct use cases.
RDS says diesel can gravity-feed from the tank bottom, giving diesel users an auxiliary-feed workflow without specifying a powered pump for that method. Gasoline use has a separate requirement: siphoning from the top with an electric fuel pump. The 45-gallon capacity is below the 69-gallon RDS model, which may suit buyers who do not need as much reserve fuel; aluminum and fully welded seams are the listed construction details to weigh.
- 45-gallon capacity
- Aluminum tank construction
- Fully welded seams
- Diesel can gravity-feed from the bottom
- Gasoline auxiliary fueling requires top siphoning with an electric fuel pump.
Skip it if you need an included high-flow pump and integrated tool storage; Vigorighter’s 60 Gallon Aluminum Fuel Transfer Tank Toolbox Combo lists both.
This RDS suits pickup owners seeking a 45-gallon aluminum tank with a stated diesel gravity-feed option. Its gasoline procedure requires an electric pump, so match the tank to the fuel and transfer method you intend to use.

8. Dee Zee DZ92556NB
- Capacity: 40 gallons
- Material: Aluminum
- Weight: 60 lb
Best for: Lightweight aluminum diesel setup.
Why it ranks #8: This 40-gallon aluminum tank has three stability baffles, mounting tabs, a drain plug, and a lockable cap, but no pump is listed.
Three stability baffles and a 40-gallon capacity give the Dee Zee DZ92556NB a practical balance for pickup-bed fuel transport. Its Brite-Tread aluminum construction is described as non-rusting, while the radius-curve design addresses weld pressure points for buyers prioritizing a lighter material than steel.
The 59-by-22-by-10-inch dimensions create a low, elongated footprint, useful for considering bed layout before mounting. Three baffles help stabilize contents, and the mounting tabs secure the tank to a truck bed. A lockable cap, venting coupler, and 3/8-inch drain plug add specified closure, ventilation, and drainage details. Dee Zee describes these transfer tanks for non-flammable liquids, so the stated application should guide fuel-use decisions rather than assuming gasoline or diesel compatibility.
- 40-gallon capacity
- Brite-Tread aluminum construction
- Three stability baffles
- Mounting tabs, lockable cap, and drain plug
- The listed application is non-flammable liquids, not gasoline or diesel.
Skip it if you need a tank explicitly specified for diesel transfer; AM-TANK 58 Diesel Pickup lists diesel use, a pump, and a tonneau-cover fit.
Consider this Dee Zee for a pickup carrying non-flammable liquids where aluminum, three baffles, and a drain plug suit the workflow. Its stated liquid-use limitation matters; do not choose it on the assumption of fuel compatibility.

9. Dee Zee DZ92556NSB
- Capacity: 128 liters
- Material: Alloy Steel
- Weight: 70 lb
Best for: Baffled steel liquid transport.
Why it ranks #9: The 42-gallon steel tank adds five stability baffles, mounting tabs, and a drain plug; its non-flammable-liquid description and no listed pump limit versatility.
Five stability baffles distinguish this 42-gallon Dee Zee steel tank, helping stabilize its contents during transport. Its 14-gauge steel body, radius-curve design, and drain plug make it a substantial option for pickup owners moving non-flammable liquids and seeking specific structural and drainage features.
The five baffles are intended to improve stability as the tank travels, while the radius curve is specified to eliminate weld pressure points. Those construction details pair with the 42-gallon capacity for transporting non-flammable liquids in a steel tank. Mounting tabs are listed to secure it to a truck bed, and the drain plug supports draining when needed. At 59.5 inches wide and 70 pounds, its dimensions and weight matter for bed placement and handling.
- 42-gallon capacity
- 14-gauge steel construction
- Five stability baffles
- Mounting tabs and drain plug
- The listed use is for non-flammable liquids, not fuel transfer.
Skip it if you need a tank explicitly listed for gasoline or diesel transfer; Better Built 29211584 specifies a 36-gallon transfer fuel tank.
This Dee Zee fits buyers transporting non-flammable liquids who value steel construction, baffles, and bed-mounting tabs. Its stated application is the key boundary: choose a different model when gasoline or diesel fuel transfer is required.

10. Better Built 36-Gallon Tank
- Capacity: 36 gallons
- Material: Alloy Steel
- Weight: 40 lb
Best for: Automatic-shutoff steel tank.
Why it ranks #10: This 36-gallon steel tank includes baffles, a lockable cap, mounting kit, and overfill restriction, but no pump is listed and capacity is lowest.
An overfill restriction that automatically shuts off at the pump is the key feature of this 36-gallon Better Built steel tank, helping limit spills during filling. Built-in baffles address shifting contents in transit, while the lockable cap and flush-mounted two-inch inlet and outlet bungs support a secure, fast-flow setup.
The 36-gallon capacity provides a defined reserve, and the overfill restriction helps manage filling by stopping flow automatically at the pump. Baffles add strength and help keep contents from shifting as the truck moves. Two-inch flush-mounted inlet and outlet bungs are specified for fast flow, while the lockable cap adds security. The alloy-steel construction and listed mounting kit with rubber bushings give buyers useful material and installation details to consider for a truck-bed setup.
- 36-gallon capacity
- Overfill restriction with automatic pump shutoff
- Built-in baffles
- Two-inch flush-mounted inlet and outlet bungs
- Its 36-gallon capacity is lower than the 40- to 69-gallon tanks listed here.
Skip it if you need more than 36 gallons of capacity; RDS MFG INC 70326 offers a listed 69-gallon auxiliary tank.
This Better Built suits pickup owners who value an automatic overfill restriction, baffles, and fast-flow bungs in a steel transfer tank. The 36-gallon capacity is the practical boundary for buyers with larger reserve-fuel needs.

View on AmazonAvoiding Fuel-Tank Fit and Fill Problems
Measure the usable bed area and cover clearance before selecting a tank, because capacity alone does not establish whether a model will fit your pickup. The AM-TANK 58-Gallon Diesel is explicitly described as low profile and designed to fit under a tonneau cover, but the listing does not provide its dimensions; confirm the measurements with the seller before ordering. Other listings do provide dimensions, including the RDS 69-Gallon Tank at 57 × 18 × 16 inches and the Vigorighter 60-Gallon Combo at 50.2 × 19.88 × 24.8 inches.
Also distinguish maximum capacity from the amount you should load: SWANGET lists a 58-gallon maximum but recommends a 52-gallon safe fill. Do not assume a nominal capacity is a safe fill limit.
Allow for fuel expansion and follow the tank’s instructions, including any stated venting requirements.
Pump, Fuel Type, and Installation Are Separate Checks
A listed transfer pump does not by itself confirm that a tank can connect to a pickup’s fuel system or legally carry every fuel type. Several products include pumps with stated flow rates: the Vigorighter 60-Gallon Combo lists 12 GPM, while the AM-TANK 58-Gallon Diesel lists 10.5 GPM. By contrast, RDS describes diesel gravity feed and auxiliary connection options, with an optional diesel install kit mentioned in its product description; its listed tank does not include a pump.
Fuel compatibility also varies: AM-TANK, SWANGET, and Wolive are identified for diesel, while the RDS 69-gallon listing says gasoline auxiliary fueling is allowed only when siphoned from the top using an electric fuel pump. Check the manufacturer’s installation instructions and applicable transport rules before use.
Confirm whether your intended setup requires separate mounting hardware, electrical connections, or an auxiliary-fueling kit.
How to Choose an In-Bed Pickup Fuel Tank
Capacity and usable fill
Choose a capacity that fits your refueling workload without treating the tank’s maximum volume as its routine fill amount. These options range from the Better Built 36-Gallon Tank to the RDS 69-Gallon Tank, with 40-, 42-, 45-, 50-, 51-, 58-, and 60-gallon choices between them. SWANGET gives a particularly clear distinction: 58 gallons maximum, with 52 gallons recommended as the safe fill.
Larger tanks may suit frequent equipment refueling, but their dimensions and loaded weight matter in a pickup bed. Buyers needing a more moderate capacity can consider the 40- to 51-gallon options; those prioritizing fewer refills may prefer a 58- to 69-gallon model, provided the bed and vehicle are suitable.
Fuel type and transfer equipment
Match the tank’s stated fuel use and included equipment to the way you intend to dispense fuel. The AM-TANK, SWANGET, and Wolive listings specify diesel use, and each includes or describes a pump; their listed rates are 10.5, 10.6, and 11.9 GPM respectively. The Vigorighter 60-Gallon Combo includes a 12 GPM pump and lists gasoline or diesel, while the 51-gallon combo lists gasoline, diesel, and kerosene.
RDS describes auxiliary fueling and diesel gravity feed, but its 69-gallon model does not list a pump. Buyers wanting powered transfer should favor a tank with a pump and hose specified; those seeking a tank for an auxiliary-fueling arrangement should verify connection and installation requirements first.
Material, bed fit, and added storage
Check both the tank material and its external dimensions against your truck bed, cover, and cargo needs. Aluminum models include the 69- and 45-gallon RDS tanks and both Vigorighter toolbox combos; steel options include Dee Zee’s 42-gallon tank and Better Built’s 36-gallon model. Polyethylene options include the AM-TANK, SWANGET, and Wolive diesel tanks.
The Vigorighter 60-Gallon Combo measures 50.2 × 19.88 × 24.8 inches overall and adds a tool compartment; the 51-gallon combo measures 50 × 19 × 21 inches and also incorporates a toolbox. Buyers who need to retain covered-bed use should investigate the AM-TANK’s low-profile design, while those needing tool storage may prefer a combo—after verifying exact clearance and fit.
Which In-Bed Fuel Tank Fits Your Pickup?
For an all-around transfer setup with a pump and tool storage, choose the Vigorighter 60-Gallon Combo; it combines a 12 GPM pump with a 60-gallon aluminum tank. If you need diesel capacity beneath a tonneau cover, consider the AM-TANK 58-Gallon Diesel, and confirm its dimensions before buying. For diesel hauling with a clearly stated safe-fill recommendation, the SWANGET 58-Gallon Diesel lists 52 gallons as its recommended fill.
Choose the RDS 69-Gallon Tank when maximum listed capacity and an auxiliary-fueling arrangement matter more than a pump included in the package. The Dee Zee DZ92556NB offers a 40-gallon aluminum option with baffles and mounting tabs.
In every case, verify bed fit, fuel compatibility, mounting, and local transport requirements before use.

Frequently Asked Questions
How do I confirm a tank will fit my pickup bed and clear its tonneau cover?
Compare the tank’s listed dimensions with your usable bed space, including wheel wells and any existing cargo or hardware. Check the tonneau’s clearance in both open and closed positions, and confirm the tank’s fill and pump access remain usable. For the AM-TANK, verify dimensions before buying, as the verdict advises.
What mounting, venting, and fuel-system rules apply to an in-bed transfer tank?
Follow the tank manufacturer’s instructions and applicable local requirements; do not assume one mounting or venting arrangement suits every tank. Confirm that the tank is compatible with the intended fuel and transfer setup, secure it as directed, and inspect connections before use. Ask a qualified installer or local authority if requirements are unclear.
Can a transfer tank legally and safely carry gasoline in my state?
That depends on the tank’s stated fuel compatibility and the transport rules that apply where you drive. Do not use a diesel-only tank for gasoline. Check state and local requirements before transport, follow the manufacturer’s instructions, and verify that the tank, fittings, and transfer equipment are suitable for the fuel.
Should I choose a tank with a pump included?
Choose based on how you plan to transfer fuel. The Vigorighter 60-Gallon Combo pairs a 60-gallon aluminum tank with a built-in 12 GPM pump and tool storage. The RDS 69-Gallon Tank has greater listed capacity, but the editorial verdict notes that a pump is not included in its package.
Should I fill a tank to its full listed capacity?
Not necessarily: listed capacity and recommended fill can differ. The SWANGET 58-Gallon Diesel lists 52 gallons as its recommended fill, so follow that guidance rather than assuming the full listed capacity is usable. Check the specific tank’s instructions and observe any applicable transport requirements before filling or carrying fuel.
Final Words
For an all-around transfer setup with a pump and tool storage, the Vigorighter 60-Gallon Combo is the strongest fit in this selection. Choose the AM-TANK 58-Gallon Diesel if keeping a tonneau closed is the priority, after confirming dimensions; choose the RDS 69-Gallon Tank if listed capacity matters more than an included pump. Before buying, verify bed fit, fuel compatibility, mounting instructions, and local transport requirements.
