A strong pickup fuel transfer tank delivers the capacity and form factor your work requires, with a secure way to transport fuel and, when needed, equipment for dispensing it. The right choice depends on whether you need a low-profile tank under a tonneau cover, a steel tank with toolbox storage, or a larger tank for fewer refills. This roundup compares 10 options spanning 36 to 116 gallons, including steel, aluminum and polyethylene models.
Some listings specify a 12V pump and hose; others describe a tank without an included transfer pump. Check those details before choosing, along with the tank’s dimensions and your truck-bed layout.
Capacity alone does not determine fit: shape, mounting arrangement and other cargo can matter just as much.
The AM-TANK 58 Gallon Diesel Transfer Tank is the best overall choice for pickup owners who need a ready-to-use, low-profile diesel setup. It holds 58 gallons, is designed to fit under a tonneau cover, and includes a 12V transfer unit with a 10.5 GPM pump, 13-foot hose and automatic shut-off nozzle. If you prioritize a larger steel tank or integrated toolbox storage instead, the Weather Guard Transfer Tank or Dee Zee Steel Combo Tank may suit your bed and work needs better.

Detailed Reviews: Best Fuel Transfer Tanks For Pickups

#1 · Best Overall
1. AM-TANK 58 Gallon Diesel Tank
- Capacity: 58 gallons
- Material: Rotomoulded Antistatic Polyethylene
Best for: Tonneau-cover refueling setup.
Why it ranks #1: Its 58-gallon low-profile design is made to fit under a tonneau cover, and the listed package includes a 12V pump, hose and automatic shut-off nozzle.
A low-profile 58-gallon tank is specified to fit under a tonneau cover, letting owners close the bed cover over their refueling supply. The AM-TANK includes a 12V pump rated at 10.5 GPM, a 13-foot dispensing hose, an automatic shut-off nozzle, and a filter for diesel transfer.
Its low-profile format is explicitly intended to sit beneath a tonneau cover, keeping the bed cover usable with the tank in place. For dispensing, the 12V, 300W pump delivers a stated 10.5 GPM through a 13-foot hose, and the automatic shut-off nozzle supports fueling equipment such as tractors, excavators, generators, and trucks. The pump has a 30-minute duty cycle, a practical operating limit for extended dispensing sessions.
- 58-gallon capacity
- Low profile specified to fit under a tonneau cover
- 12V pump rated at 10.5 GPM
- 13-foot hose with automatic shut-off nozzle and filter
- The pump has a 30-minute duty cycle.
Skip it if you need continuous pumping beyond a 30-minute duty cycle; the VEVOR 116-gallon tank lists a 10.6 GPM pump without that stated runtime limit.
This AM-TANK suits diesel users who want a covered bed and an included powered refueling setup for equipment or vehicles. Its 30-minute pump duty cycle matters for longer dispensing sessions.

#2 · Best Steel Tank
2. Weather Guard L-Shape Tank
- Capacity: 90 gallons
- Material: Alloy Steel
- Weight: 196 lb
Best for: Full-size truck bed capacity.
Why it ranks #2: The 90-gallon, 12-gauge steel tank is designed for full-size trucks with gull-wing or saddle boxes and has interior baffles to limit fluid movement.
A 90-gallon capacity paired with an L-shaped profile gives the Weather Guard tank room for substantial fuel reserves while accommodating full-size trucks with Gull Wing or Saddle Boxes. Its heavy-duty 12-gauge steel construction suits demanding transport, and interior baffles help control fuel movement on the road.
The L-shape is specifically identified for full-size trucks with Gull Wing or Saddle Boxes, making that bed configuration the key fit consideration. Inside, baffles minimize fluid motion, helping reduce sloshing as the truck travels. A 3/8-inch drain port supports routine cleaning, while the 2-inch NPT connection accommodates a pump connection. At 196 pounds, this steel tank is a substantial installation, so plan for its weight as well as its 90-gallon capacity.
- 90-gallon fuel capacity
- L-shape works with Gull Wing or Saddle Boxes
- 12-gauge steel construction
- Baffles minimize fluid motion
- At 196 pounds, the tank is heavy to position during installation.
Skip it if you need a lighter tank to maneuver into the bed; the 70-pound DEE ZEE DZ92556NSB is listed at a lower weight.
Choose this Weather Guard for a full-size truck owner who needs 90 gallons and has a Gull Wing or Saddle Box configuration. Its 196-pound weight makes positioning a key installation consideration.

#3 · Best Tank and Toolbox
3. Dee Zee Steel Combo Tank
- Capacity: 92 gallons
- Material: Alloy Steel
- Weight: 49 lb
Best for: Large-capacity combo storage.
Why it ranks #3: This 92-gallon L-shaped steel combo adds storage to the transfer tank, with a powder-coated finish, stability baffle, lockable cap and drain plug.
A 92-gallon tank combined with toolbox storage gives the DEE ZEE DZ92647SB a two-purpose layout for truck owners carrying fuel and equipment. Its L-shape measures 46.75 by 32.75 by 25.375 inches, and 14-gauge steel with a corrosion-inhibiting NRT powder coat forms its construction.
The L-shaped 92-gallon tank pairs fuel capacity with bolted-on storage, so one combo unit serves both roles in the bed. The stated 46.75-inch length, 32.75-inch width, and 25.375-inch height help assess its footprint before installation. Dee Zee identifies 14-gauge steel and an NRT powder coat intended to increase corrosion protection; its radius-curve construction also addresses weld pressure points, while a stability baffle helps steady contents.
- 92-gallon capacity
- Bolted-on toolbox storage
- 14-gauge steel construction
- NRT powder coat intended to increase corrosion protection
- Its 32.75-inch width and 25.375-inch height require substantial bed space.
Skip it if you need to preserve more open bed area; the 42-gallon DEE ZEE DZ92556NSB is a tank without the listed combo toolbox storage.
Choose the DZ92647SB if your truck work calls for a large fuel reserve and attached toolbox storage. Its 92-gallon capacity and stated footprint make bed space the central fit consideration.

#4 · Portable Tank Option
4. CAMMOO 58 Gallon Tank
- Capacity: 58 gallons
- Material: Aluminum, High Density Polyethylene (HDPE)…
- Weight: 68.8 lb
Best for: Portable tank for outdoor use.
Why it ranks #4: The 58-gallon tank lists a 13.2 GPM flow rate, outdoor-resistant LLDPE and HDPE construction, and a combo lock for access security.
A stated 58-gallon real capacity gives the CAMMOO portable tank a substantial diesel reserve, while flame-retardant LLDPE and HDPE construction is specified for outdoor conditions. Its listed resistance to UV, rain, snow, wear, and corrosion suits users moving fuel among work sites within the stated operating temperature range.
The LLDPE and HDPE tank materials are described as resisting UV exposure, rain, snow, wear, and corrosion, supporting outdoor placement and transport. CAMMOO also states that it meets DOT requirements. The listed use range is 14°F to 104°F with fuel inside, which is an important operating boundary for seasonal work. A combo lock is specified for securing fuel and simplifying routine access; the product title identifies a 12V DC system rated at 13.2 GPM.
- 58-gallon capacity
- LLDPE and HDPE construction
- Listed resistance to UV, rain, snow, wear, and corrosion
- Combo lock for securing stored fuel
- The stated operating range with fuel inside is 14°F to 104°F.
Skip it if you work outside 14°F to 104°F with fuel inside the tank; the VEVOR 116-gallon listing does not state that temperature restriction.
The CAMMOO suits outdoor users who need a portable 58-gallon diesel supply and value a combo lock. Keep its specified 14°F-to-104°F operating range in mind when planning seasonal use.

#5 · Highest Capacity
5. VEVOR 116 Gallon Diesel Tank
- Capacity: 116 gallons
- Material: Polyethylene (PE)
- Weight: 104.1 lb
Best for: High-capacity powered diesel supply.
Why it ranks #5: Its 116-gallon polyethylene tank includes a 12V DC pump rated at 10.6 GPM and a 13.1-foot hose, for buyers prioritizing large diesel capacity.
A 116-gallon capacity paired with a 12V pump rated at 10.6 GPM makes the VEVOR a high-volume portable diesel refueling setup. Its polyethylene tank is listed as UV-resistant and able to handle changing weather conditions, while a lockable copper-lock lid adds a security measure for stored fuel.
The 12V DC pump’s stated 10.6 GPM maximum flow and 13.1-foot hose support dispensing from the tank to equipment or vehicles without relying on a separate listed pump. The 116-gallon capacity provides a large reserve, while the 6mm thickness, reaching 12mm at the thickest part, describes the tank construction. Its 28.3-inch width and 28.9-inch height help with placement planning; the lid locks with a copper lock.
- 116-gallon capacity
- 12V DC pump with 10.6 GPM maximum flow
- 13.1-foot hose
- Lockable lid and UV-resistant polyethylene construction
- Its 116-gallon capacity and 104.1-pound weight make it a substantial portable load.
Skip it if you need a tank specified to fit beneath a tonneau cover; the AM-TANK 58 is explicitly low-profile for that arrangement.
The VEVOR suits users who need a very large portable diesel reserve and included powered dispensing. Its 116-gallon capacity, 104.1-pound weight, and listed dimensions make placement and handling central considerations.

6. ATI 95 Gallon Refueling Tank
- Capacity: 95 gallons
- Material: Aluminum
- Weight: 137 lb
Best for: DOT-permitted multi-fuel capacity.
Why it ranks #6: The 95-gallon aluminum tank is listed for trucks and SUVs, with full baffles and a DOT special permit for several specified fuels and liquids.
A US Department of Transportation special permit is the defining feature of the ATI TTL95, which is listed for gas, diesel, methanol, kerosene, aviation fuel, and other liquids. Its 95-gallon aluminum diamond-plate tank is fully baffled to reduce movement of contents during transport.
The stated special permit covers multiple fuel types, giving buyers a listed basis for considering fuels beyond diesel, including gasoline and aviation fuel. At 95 gallons, the tank carries a large reserve, while full baffling helps reduce contents’ movement in transit. The lockable vent/prevent filler cap adds a locking closure, and the 52-by-48-by-33-inch dimensions plus 137-pound weight are important bed-space and handling factors.
- 95-gallon capacity
- Special permit listed for multiple fuels
- Aluminum diamond-plate construction
- Fully baffled to reduce movement of contents
- At 137 pounds and 52 by 48 by 33 inches, it is a large, heavy tank to position.
Skip it if you need a smaller portable diesel tank with an included 12V pump; the VEVOR 116-gallon model lists a 10.6 GPM pump.
The ATI TTL95 fits truck or SUV owners who need a large, baffled tank with a stated multi-fuel special permit. Its 52-by-48-inch footprint and 137-pound weight are key fit and handling limits.

7. Dee Zee 42 Gallon Tank
- Capacity: 128 liters
- Material: Alloy Steel
- Weight: 70 lb
Best for: Baffled steel tank with mounting tabs.
Why it ranks #7: Its 42-gallon steel tank has five stability baffles, mounting tabs and a drain plug, making it a more modest-capacity option for a pickup bed.
Five stability baffles and mounting tabs give the DEE ZEE DZ92556NSB a practical focus on steadier transport and bed security. Its 14-gauge steel body holds 42 gallons, while the radius curve is intended to eliminate weld pressure points for buyers seeking a compact steel transfer tank.
The five stability baffles help limit fuel movement as the truck is underway, and the mounting tabs provide points to secure the tank to the bed. A radius-curve design eliminates weld pressure points, while the black NRT powder-coat finish is described as a rust inhibitor. The 59.5-inch width and 19-inch height are useful bed-planning dimensions; at 70 pounds, it is lighter than the 196-pound Weather Guard 90-gallon tank.
- 42-gallon capacity
- Five stability baffles
- Mounting tabs for securing it to the truck bed
- Radius curve eliminates weld pressure points
- Its 42-gallon capacity is smaller than high-volume options in this roundup.
Skip it if you need more than 42 gallons aboard; the Weather Guard 354-5-02 offers 90 gallons for compatible full-size truck beds.
This DEE ZEE suits truck owners who want a steel tank with bed-mounting tabs and baffles in a 42-gallon size. Check the listed 59.5-inch width and 19-inch height against your available bed space.

8. RDS 45 Gallon Aluminum Tank
- Capacity: 45 gallons
- Material: Aluminum
- Weight: 42 lb
Best for: Aluminum tank for gasoline transfer.
Why it ranks #8: This 45-gallon aluminum tank has fully welded seams and avoids rusting; the listing specifies gasoline auxiliary fueling only when pumped from the top.
An aluminum body with fully welded seams gives the RDS 71083 a rust-free construction claim and a 45-gallon capacity. RDS lists gasoline auxiliary fueling when fuel is siphoned from the tank’s top using an electric fuel pump, a specific setup that matters to gasoline users.
The aluminum construction is described as not rusting, while fully welded seams provide the stated durability feature. For gasoline auxiliary fueling, RDS specifies siphoning from the top of the tank with an electric fuel pump, so buyers should plan around that method rather than assuming bottom gravity feed. The 45-gallon capacity offers a moderate reserve, and the 42-pound listed weight is relevant when handling and positioning the tank.
- 45-gallon capacity
- Aluminum construction described as not rusting
- Fully welded seams
- Gasoline auxiliary fueling permitted with top siphoning and an electric pump
- Gasoline auxiliary fueling requires top siphoning with an electric fuel pump.
Skip it if you want a stated DOT special permit covering gas and diesel; the ATI TTL95 lists that permit and a 95-gallon capacity.
Choose the RDS 71083 if you want a 45-gallon aluminum tank and can use its specified top-siphon method for gasoline. Its 42-pound listed weight helps with handling plans.

9. RDS 60 Gallon Toolbox Tank
- Capacity: 60 gallons
- Material: Alloy Steel, Aluminum, Stainless Steel
- Weight: 16 oz
Best for: Auxiliary-fueling toolbox combo.
Why it ranks #9: The 60-gallon steel toolbox combo is intended for truck use, but its listed details provide less clarity about dimensions and included transfer equipment.
A 60-gallon transfer tank that can also provide auxiliary fueling makes the RDS 72548 a combination option for truck owners seeking stored fuel and a toolbox in one unit. RDS describes diesel gravity feed from the tank bottom, with an optional Diesel Install Kit for installation.
The 60-gallon capacity supplies a substantial onboard reserve, while the combo format pairs the tank with toolbox functionality rather than requiring a separate storage unit. RDS says its transfer tanks can provide auxiliary fueling by connecting to the vehicle fuel tank; diesel can gravity feed from the tank bottom. The 55-by-20-by-19.5-inch dimensions help assess bed space, and the optional Diesel Install Kit is a separate installation consideration.
- 60-gallon capacity
- Transfer tank and toolbox combo format
- RDS describes diesel gravity feed from the tank bottom
- 55-by-20-by-19.5-inch dimensions provided for planning
- The Diesel Install Kit is optional rather than included as standard.
Skip it if you want a listed ready-to-use 12V pump and dispensing hose; the AM-TANK 58 includes a 12V transfer unit and 13-foot hose.
The RDS 72548 fits truck owners who want 60 gallons, toolbox functionality, and the option of auxiliary diesel fueling. Account for its listed dimensions and the optional Diesel Install Kit when planning installation.

10. Better Built 36 Gallon Tank
- Capacity: 36 gallons
- Material: Alloy Steel
- Weight: 40 lb
Best for: Compact tank with overfill shutoff.
Why it ranks #10: This 36-gallon steel tank includes a mounting kit and lockable cap, but its listing gives limited bed-fit detail compared with the other pickup-focused options.
An overfill restriction that automatically shuts off at the pump is the Better Built tank’s key differentiator, helping limit spills during filling. Its 36-gallon rectangular steel body also has built-in baffles, flush-mounted two-inch inlet and outlet bungs, and a lockable cap for a work-truck fuel setup.
The overfill restriction provides an automatic pump shutoff, giving filling a clear spill-control safeguard. Built-in baffles add strength while helping keep contents from shifting during transport. Flush-mounted two-inch inlet and outlet bungs support fast flow, and the lockable cap adds a security measure when the tank is stored in the truck. Its 36-gallon capacity and listed 11-by-17-inch dimensions suit buyers prioritizing this feature set over a larger reserve.
- Automatic pump shutoff from the overfill restriction
- Built-in baffles add strength and limit shifting
- Two-inch flush-mounted inlet and outlet bungs
- Vented lockable cap
- The 36-gallon capacity is limited for buyers needing a larger reserve.
Skip it if you need a reserve above 36 gallons; the 90-gallon Weather Guard 354-5-02 provides substantially more capacity for compatible beds.
Pick the Better Built for a truck owner who values an automatic overfill shutoff, baffles, and fast-flow two-inch bungs in a 36-gallon tank. Its listed dimensions and capacity set the bed-planning boundary.

Listed on Amazon as: Better Built Steel Transfer Fuel Tank – 36-Gallon, Rectangular, Black, Model Number 29211584
View on AmazonCheck the transfer setup before planning a refill
A tank’s listed capacity does not tell you whether it arrives ready to dispense fuel. The AM-TANK 58 Gallon Diesel Tank lists a 12V transfer unit, a 13-foot hose and an automatic shut-off nozzle, while the VEVOR 116 Gallon Diesel Tank lists a 12V pump and 13.1-foot hose. Several steel and aluminum entries focus on the tank itself and do not list a pump among their supplied components.
Treat that difference as a planning issue: verify which pump, hose, electrical connections and fittings are included before assuming you can refuel equipment straight from the bed. A mismatched connection or missing component can leave a filled tank unusable for the intended job until you source compatible parts.
Also distinguish transfer from auxiliary fueling; the RDS descriptions discuss different ways of connecting or drawing fuel, not a universal feature of every tank.
Treat bed shape and cover clearance as fit constraints
A tank’s gallon rating cannot confirm that it fits your truck bed or clears a bed cover. The AM-TANK 58 Gallon Diesel Tank is specifically described as low profile and designed to fit under a tonneau cover, while the Weather Guard L-Shape Tank is described for full-size trucks with gull-wing or saddle boxes. The Dee Zee Steel Combo Tank is also L-shaped, with listed dimensions of 46.75 by 32.75 by 25.375 inches.
Those different profiles can affect usable cargo space, cover clearance and access to other bed equipment. Before buying, compare the product’s dimensions and shape with your truck’s available footprint, cover hardware, wheel wells and planned cargo.
Do not assume that two tanks of similar capacity occupy the same space: this set includes both rectangular and L-shaped designs, and the product listings do not establish compatibility with every pickup.
How to Choose a Pickup Transfer Tank
Capacity and bed-space trade-off
Choose a capacity that matches your work while leaving enough usable bed space. This lineup ranges from the Better Built 36 Gallon Tank to the VEVOR 116 Gallon Diesel Tank; the Weather Guard holds 90 gallons, and the AM-TANK holds 58 gallons. Larger tanks can carry more fuel between refills, but their listed capacity does not show whether they fit a particular bed or how much cargo room remains.
Buyers needing a moderate load and a tonneau-compatible profile may prefer the 58-gallon AM-TANK. Those who prioritize fewer refills and can accommodate a larger tank can consider the 90- to 116-gallon options, after checking dimensions against the truck.
Material and construction
Match the tank material and construction to your intended use and upkeep preferences. The steel options include 12-gauge steel on the Weather Guard and 14-gauge steel on the Dee Zee 42 Gallon Tank; the RDS 45 Gallon Aluminum Tank uses aluminum with fully welded seams, while the AM-TANK and VEVOR tanks use polyethylene-based materials. Several listings describe baffles, which can limit contents shifting, but construction details vary by model.
Steel models may appeal when you want a metal tank or combo storage, while aluminum or polyethylene options may suit buyers seeking those specific materials. Confirm the fuel compatibility and applicable requirements for your intended use rather than inferring them from material alone.
Included transfer equipment and storage
Check whether the package includes dispensing equipment or adds useful truck-bed storage. The AM-TANK lists a 12V pump, hose and automatic shut-off nozzle, while the VEVOR lists a 12V pump and hose; many other listings describe a tank without listing a pump. For combined cargo storage, the Dee Zee Steel Combo Tank and RDS 60 Gallon Toolbox Tank pair tank and toolbox formats.
The Better Built 36 Gallon Tank lists a mounting kit and lockable cap, but not a pump. A buyer who needs to refuel machinery on site may favour a package with a listed pump and hose; someone who already has compatible equipment may prefer to compare tank shape, capacity and storage instead.

For a pickup owner who wants a tonneau-cover-compatible diesel setup with dispensing equipment listed, choose the AM-TANK 58 Gallon Diesel Tank. For full-size trucks with gull-wing or saddle boxes and a preference for heavy-gauge steel, the Weather Guard L-Shape Tank offers 90 gallons. If toolbox storage matters alongside fuel capacity, consider the 92-gallon Dee Zee Steel Combo Tank or the RDS 60 Gallon Toolbox Tank.
Choose the VEVOR 116 Gallon Diesel Tank when maximum listed diesel capacity and a specified pump matter more than compactness. For a smaller steel option, the Dee Zee 42 Gallon Tank has five stability baffles.
Check dimensions, fuel compatibility, included equipment and truck-bed clearance before ordering; these listings do not establish fit for every pickup.

Frequently Asked Questions
How do I confirm that a transfer tank will fit my pickup bed and tonneau cover?
Measure the available bed space and clearance beneath the closed tonneau cover, then compare those measurements with the tank’s listed dimensions. Check how the tank’s shape and any toolbox affect access to the bed. Listings do not establish fit for every pickup, so confirm compatibility for your truck before ordering.
Do I need a separate pump, hose, wiring and mounting hardware for a transfer tank?
Check the product listing for each included item rather than assuming a tank comes ready to dispense fuel. The AM-TANK listing specifies a 12V pump, hose, automatic shut-off nozzle and filter; other listings may not specify these components. Confirm wiring and mounting hardware requirements with the seller or manufacturer before purchase.
Which transfer tank materials and designs are appropriate for the fuel I plan to carry?
Choose a tank explicitly listed as compatible with the fuel you intend to carry, and verify that compatibility with its manufacturer. The listings identify some tanks as diesel-only and one as suitable for gas or diesel; do not infer fuel compatibility from material or appearance alone. Match the tank’s design to your bed and storage needs.
How much tank capacity should I choose for my pickup?
Choose capacity based on how much fuel you need to carry and how much bed space you can give up. The listed options range from 36 to 116 gallons, but a larger tank is not automatically the right fit. Check your truck’s payload limits and the filled tank’s weight before deciding.
What should I check before installing and using a transfer tank?
Verify the tank’s dimensions, fuel compatibility, included equipment and mounting requirements before installation. Confirm that the tank can be secured in your particular bed and that the setup works with any cover or toolbox. Follow the manufacturer’s instructions and applicable requirements for carrying and dispensing the fuel you plan to use.
Final Words
For a ready-to-use, low-profile diesel setup under a tonneau cover, the AM-TANK 58 Gallon Diesel Transfer Tank is the strongest match in this roundup. Consider the Weather Guard 90-gallon tank for a larger steel option, or the Dee Zee and RDS combo designs when toolbox storage matters. Before choosing, compare dimensions, fuel compatibility, included dispensing equipment, mounting needs and truck-bed clearance; no listing establishes fit for every pickup.
