A strong extra truck tank adds useful fuel capacity while matching your truck-bed space, fuel type, and transfer needs; the Vigorighter 51-gallon aluminum combo is the most complete listed package for buyers who want a tank, toolbox, and pump together. This roundup compares seven options, from compact steel tanks to large-capacity combos and diesel-focused pump systems. Capacities range from 36 to 92 gallons, and materials include aluminum, alloy steel, and polyethylene.
Those differences matter: a larger tank needs more room and adds more weight when full, while a pump-equipped system can simplify dispensing but may be limited to a stated fuel type. Check dimensions, intended fuel compatibility, mounting requirements, and local transport rules before buying; listed specifications alone do not confirm fit or regulatory compliance.
The Vigorighter 51-Gallon Combo leads because it combines a 51-gallon aluminum tank, built-in toolbox, and 12 GPM 12V DC pump in one listed package. It is the strongest fit for truck owners who want storage and transfer equipment together, rather than a bare tank. Its listed footprint is about 50–58 inches long by 19 inches wide, so measure the bed before choosing it.
Confirm fuel compatibility and applicable transport requirements before use.

Detailed Reviews: Best Extra Gas Tank For Trucks
#1 · Best Overall
1. Vigorighter 51-Gallon Combo
- Capacity: 51 gallons
- Material: Aluminum
Best for: Fuel-and-toolbox haulers.
Why it ranks #1: Pairs 51-gallon aluminum storage with a built-in toolbox and 12 GPM 12V pump; the listing names gasoline, diesel, and kerosene.
A 51-gallon tank paired with a built-in 31-inch toolbox lets truck owners carry fuel and organize tools in one unit. Vigorighter adds a 12 GPM, 12V DC pump, 13-foot hose, and automatic nozzle, making this combo a ready-to-transfer option for gasoline, diesel, or kerosene.
The aluminum construction is described as corrosion-resistant, while the 51-gallon capacity provides a substantial onboard reserve. Its toolbox measures 31 by 19 by 8.8 inches, giving tools a dedicated compartment rather than leaving them loose alongside cargo. The listed 12 GPM pump and 13-foot hose support fuel transfer from the truck bed, and the automatic nozzle is part of the package. The overall footprint is about 50 to 58 inches long, depending on the supplied dimension listing.
- 51-gallon capacity
- Built-in 31-inch toolbox
- 12 GPM 12V DC pump with 13-foot hose
- Automatic nozzle; listed for gasoline, diesel, and kerosene
- Its 51-gallon capacity is less than the 92-gallon DEE ZEE DZ92647SB.
Skip it if you need the greatest listed capacity in a tank-and-toolbox combo; the DEE ZEE DZ92647SB holds 92 gallons.
For truck owners who want fuel transfer equipment and a separate tool compartment in one aluminum unit, this is a practical match. Account for its roughly 50-inch-plus length and 19-inch width when planning bed space.

2. BreAro 58-Gallon Tank
- Capacity: 58 gallons
- Material: High Density Polyethylene (HDPE)
Best for: Diesel transfer operators.
Why it ranks #2: Includes a 10.6 GPM 12V transfer pump and filter with 58-gallon HDPE capacity; its stated pump use is diesel, not gasoline.
A 10.6 GPM, 12V DC transfer pump comes with this 58-gallon BreAro tank, enabling diesel transfer without a separate pump purchase. A built-in filter supports clean fuel delivery, and the included 13.1-foot power cord connects the pump to a power source during operation.
The 58-gallon HDPE tank gives diesel users a large reserve in a polyethylene container described as resistant to scratches and dents. Its pump is rated at 10.6 GPM, and the built-in filter supports fuel delivery through the transfer system. The 13.1-foot power cord provides reach for connecting the 12V pump, making the package more self-contained for refueling equipment or vehicles where a suitable power source is available.
- 58-gallon capacity
- 12V DC pump rated at 10.6 GPM
- Built-in filter
- 13.1-foot power cord
- This tank and pump are specified for diesel, not gasoline.
Skip it if you need a tank for gasoline as well as diesel; the Vigorighter 51-gallon combo is listed for both fuels.
Diesel users needing a high-capacity portable tank with its own pump and filter should consider this package. Its listed diesel application and 13.1-foot cord are important operating boundaries.

3. STMGW 45-Gallon Tank
- Capacity: 45 gallons
- Material: Aluminum
- Weight: 40 lb
Best for: Slim aluminum tank buyers.
Why it ranks #3: Offers 45 gallons in a 57-by-9.5-by-20-inch aluminum rectangular format, useful when a narrow tank profile suits the truck-bed layout.
A 9.5-inch width gives the STMGW 45-gallon tank a notably narrow rectangular profile, helping truck owners reserve more bed width for other cargo. Its aluminum construction is described as lightweight and corrosion-resistant, and the tank is listed for liquid fuel storage and transfer applications.
The 57-by-9.5-by-20-inch dimensions make this a long, narrow option rather than a bulky square tank, which can help buyers plan around other bed cargo. Its 45-gallon capacity provides an onboard fuel reserve, while aluminum construction is associated in the supplied details with corrosion resistance and lighter weight. The product is identified for truck use and includes a top transmission interface, though no further interface details are provided.
- 45-gallon capacity
- Narrow 9.5-inch width
- Aluminum construction
- Listed for truck mounting and liquid fuel storage or transfer
- Its 57-inch length requires a long mounting area in the truck bed.
Skip it if you need a transfer pump included with the tank; the BreAro 58-gallon model lists a 12V DC pump.
For truck owners seeking a narrow aluminum tank for fuel storage or transfer, the STMGW offers a 45-gallon option. Its 57-inch length is the key fit boundary when arranging bed space.

4. Better Built 36-Gallon Tank
- Capacity: 36 gallons
- Material: Alloy Steel
- Weight: 40 lb
Best for: Baffled steel fuel haulers.
Why it ranks #4: Its 36-gallon alloy-steel tank includes baffles, a lockable cap, mounting kit, and overfill restriction with automatic pump shutoff.
An overfill restriction that automatically shuts off at the pump gives the Better Built 36-gallon steel tank a spill-control feature at the fill point. Built-in baffles also help prevent contents from shifting during transport, making this rectangular tank a straightforward choice for work-truck fuel storage.
The 36-gallon capacity suits buyers who want a sizable reserve without stepping up to the larger tanks in this group. Its baffles add strength and limit fuel movement as the truck travels, while the overfill restriction is intended to stop filling before spillage. Flush-mounted two-inch inlet and outlet bungs support fast flow, and the included vented lockable cap and mounting kit with rubber bushings address closure and mounting needs.
- 36-gallon capacity
- Automatic pump shutoff overfill restriction
- Built-in baffles help limit shifting
- Flush-mounted 2-inch inlet and outlet bungs
- At 36 gallons, its capacity is below the 45-gallon STMGW tank.
Skip it if you need at least 45 gallons of reserve; the STMGW 45-gallon rectangular aluminum tank offers more listed capacity.
Choose this steel tank for a work truck where baffles, an overfill shutoff, and flush-mounted two-inch bungs matter. Its 36-gallon capacity is the boundary for buyers who need more fuel onboard.

5. DIYTUNINGS 58-Gallon Tank
- Capacity: 58 gallons
- Material: Aluminum
Best for: Gauge-equipped tank owners.
Why it ranks #5: Provides 58 gallons in aluminum, with a sending unit for a fuel gauge and listed dimensions of 60 by 13.4 by 18.8 inches.
A sending unit that connects to a fuel gauge lets the driver check remaining capacity in this 58-gallon DIYTUNINGS aluminum tank. Oil pipes and vent covers are also listed, making it a high-capacity liquid-storage choice with components for fuel connection and venting.
The 58-gallon capacity provides a large onboard reserve, while the aluminum construction is described as lightweight and easy to clean. An electroplated surface finish is specified to help prevent rust. The listed sending unit connects to a fuel gauge, supporting at-a-glance monitoring of the remaining contents; oil pipes and vent covers are also included among its features. Its stated dimensions are approximately 60 by 13.4 by 18.8 inches.
- 58-gallon capacity
- Sending unit connects to a fuel gauge
- Aluminum construction is described as lightweight and easy to clean
- Electroplated finish intended to prevent rust
- The listed application is diesel fuel, limiting buyers seeking a gasoline tank.
Skip it if you need an included powered transfer pump; the BreAro 58-gallon diesel tank lists a 10.6 GPM 12V pump.
This suits truck owners who want a 58-gallon aluminum tank with gauge-connected level monitoring. Its diesel listing and roughly 60-inch length are important fuel-use and bed-fit considerations.

6. Dee Zee 92-Gallon Combo
- Capacity: 92 gallons
- Material: Alloy Steel
- Weight: 49 lb
Best for: High-capacity combo users.
Why it ranks #6: The 92-gallon steel L-shaped combo adds tool storage, a stability baffle, and a lockable cap, but the listing specifies non-flammable liquids.
The 92-gallon capacity is the defining feature of the DEE ZEE DZ92647SB, while its L-shaped form combines fuel storage with bolted-on tool storage. A 14-gauge steel tank and NRT powder-coat finish bring a protective exterior to a high-volume truck-bed setup.
The L-shaped tank measures 46.75 by 32.75 by 25.375 inches, so buyers can plan around its broad footprint before allocating the rest of the bed. Its bolted-on storage puts a tool compartment alongside the tank, helping keep equipment together with the fuel supply. The 14-gauge steel construction and NRT corrosion-protection coating support a durable work-truck installation, while the 92-gallon capacity reduces reliance on smaller onboard reserves.
- 92-gallon capacity
- L-shaped tank with bolted-on storage
- 14-gauge steel construction
- NRT powder coat for corrosion protection
- Its 46.75-by-32.75-inch footprint takes substantial truck-bed space.
Skip it if you have limited bed room or want a slimmer tank; the STMGW 45-gallon model is only 9.5 inches wide.
This is suited to truck owners who prioritize a very large reserve and integrated storage for work gear. Its L-shaped, 32.75-inch-wide footprint calls for careful bed-space planning before installation.

7. Dee Zee 55-Gallon Square
- Capacity: 55 gallons
- Material: Alloy Steel
- Weight: 28 lb
Best for: Square steel tank users.
Why it ranks #7: This 55-gallon steel square tank has a white protective powder coat and baffle, but its description limits transport to non-flammable liquids.
A square, 55-gallon steel tank gives the DEE ZEE DZ91750S a compact, upright shape for truck owners seeking substantial liquid capacity. Its white powder-coat finish is specified for corrosion protection, and the radius-curve construction addresses pressure points at the welds.
The 24-by-24-by-24-inch square profile, with listed dimensions of 28 by 25 by 25 inches, calls for a roughly box-shaped mounting area in the truck bed. A stability baffle helps manage movement during transport, while the lockable cap secures the opening. The 3/8-inch drainage plug supports draining, and the white NRT powder coat is intended to protect the steel against corrosion. The supplied description identifies it for transporting non-flammable liquids.
- 55-gallon listed capacity
- Square steel construction
- White NRT powder coat for corrosion protection
- Stability baffle, lockable cap, and 3/8-inch drain plug
- Its square profile needs roughly 25 inches of bed width and height.
Skip it if you need a tank-and-toolbox combination; the DEE ZEE DZ92647SB pairs fuel storage with bolted-on tool storage.
Truck owners wanting a square steel tank for non-flammable liquid transport can value its baffle, lockable cap, and drain plug. Plan for the roughly 25-inch square profile when checking available bed area.

View on AmazonFuel type is a compatibility trap
A tank described as a transfer tank is not automatically suitable for every fuel, so verify the exact liquid before buying or filling it. The Vigorighter listing names gasoline, diesel, and kerosene, while the BreAro pump is specified for diesel. The STMGW description calls its 45-gallon tank suitable for liquid fuel storage and transfer but does not identify specific fuels in the supplied facts.
Both Dee Zee descriptions explicitly describe transporting non-flammable liquids, which makes them poor choices for a buyer seeking a gasoline tank despite their substantial capacities. The DIYTUNINGS product is titled and described as a diesel tank.
Do not infer gasoline compatibility from material alone: aluminum, steel, or polyethylene construction does not establish compatibility of fittings, seals, vents, or pump. Check the complete manufacturer instructions and applicable requirements before use, and do not put fuel into a tank whose approved contents are unclear.
Measure the full bed footprint before ordering
A tank’s capacity does not tell you whether its shape will fit your truck bed or leave useful cargo space. The Vigorighter combo is about 50 inches long and 19 inches wide in the verified dimensions, while its toolbox is listed at 31 by 19 by 8.8 inches; the title separately gives an overall length of 58.1 inches, so confirm the exact configuration dimensions. The STMGW tank is 57 inches long but only 9.5 inches wide, a different footprint from the 60-by-13.4-inch DIYTUNINGS tank.
The Dee Zee 92-gallon combo uses an L shape measuring 46.75 by 32.75 by 25.375 inches, and the square Dee Zee is listed at 28 by 25 by 25 inches. Compare dimensions with bed rails, wheel wells, cargo, and access to the filler and pump.
Also confirm mounting points and loaded weight; capacity and empty product weight do not state the full operating load.
How to Choose a Truck Fuel Transfer Tank
Capacity and bed footprint
Choose a capacity that fits your expected fuel use without taking more bed space than you can spare. The listed range runs from 36 gallons for the Better Built tank to 92 gallons for the Dee Zee combo; other options include 45, 51, 53/55, and 58 gallons. Shape changes the fit as much as volume: STMGW measures 57 by 9.5 by 20 inches, whereas the Dee Zee L-shaped combo is 46.75 by 32.75 by 25.375 inches.
A narrow bed layout may favour the STMGW profile, while buyers who need more storage capacity may consider the 92-gallon unit only if its footprint and non-flammable-liquid limitation match their needs. Measure the available space and verify dimensions with the seller, especially where supplied listings show differing figures.
Material and intended fuel
Match the tank’s listed material and stated fuel use to the liquid you plan to carry, and verify approval before filling it. The options include aluminum on the Vigorighter, STMGW, and DIYTUNINGS tanks; alloy steel on both Better Built and Dee Zee products; and HDPE on BreAro. Fuel statements differ: Vigorighter names gasoline, diesel, and kerosene, while BreAro specifies a diesel pump and DIYTUNINGS is presented as a diesel tank.
Dee Zee describes its tanks for non-flammable liquids, so those models should not be treated as gasoline options based on capacity alone. Buyers prioritizing a listed gasoline use should investigate Vigorighter’s instructions; a diesel-only transfer setup may favour BreAro.
Material by itself does not establish fuel compatibility, durability in a particular environment, or legal approval.
Transfer equipment and storage features
Decide whether you need a pump and tool storage included, or only a tank to connect to separate equipment. Vigorighter combines its 51-gallon tank with a 12 GPM 12V pump, hose, auto nozzle, and toolbox; BreAro supplies a 10.6 GPM 12V pump and built-in filter for diesel. By contrast, Better Built lists a transfer tank, vented lockable cap, mounting kit, baffles, and overfill restriction, but no pump in the supplied components.
The Dee Zee 92-gallon combo adds tool storage, while the smaller Dee Zee lists a stability baffle and lockable cap. A buyer wanting a ready-to-transfer diesel system may prefer BreAro; someone seeking an integrated toolbox and pump may favour Vigorighter.
Confirm wiring, hoses, fittings, mounting hardware, and installation needs before assuming a listed system is ready for your truck.
Which Extra Truck Tank Should You Choose?
For a combined tank, toolbox, and pump, choose Vigorighter 51-Gallon Combo: it is the most complete listed package and names gasoline among its intended fuels. If you need a diesel-focused pumped setup, BreAro 58-Gallon Tank includes a 10.6 GPM 12V pump and filter. Choose STMGW 45-Gallon Tank when its narrow 9.5-inch width suits your available bed space, or Better Built 36-Gallon Tank if you prefer steel with baffles, an overfill restriction, and a mounting kit.
DIYTUNINGS 58-Gallon Tank offers aluminum diesel storage and a sending unit. Dee Zee 92-Gallon Combo gives the most capacity and toolbox storage, but its listing specifies non-flammable liquids; Dee Zee 55-Gallon Square has the same stated limitation.
Verify fuel compatibility, fit, mounting, and legal requirements before purchase.

Frequently Asked Questions
Are auxiliary fuel tanks legal to carry on public roads where I live?
Check the transport rules that apply where you live before carrying fuel on public roads. Requirements can depend on location, fuel type, and how the tank is installed. Confirm applicable rules with the relevant authorities, and verify that the specific tank is suitable for your intended fuel and transport use.
How do I secure and plumb a transfer tank in my truck bed?
Follow the tank and pump manufacturers’ installation instructions, and confirm the tank fits your bed before mounting. Use appropriate mounting hardware and connect the pump, hose, and nozzle as directed. Some listings include a mounting kit or pump equipment; do not assume those items are included unless the product details say so.
Can a truck transfer tank safely store gasoline, diesel, or both?
Use only fuel types explicitly listed as compatible for the tank. The Vigorighter listing names gasoline, diesel, and kerosene, while several other listed tanks are described for diesel. Both Dee Zee listings specify non-flammable liquids, so do not assume they are suitable for gasoline or diesel.
Verify compatibility before use.
What measurements should I check before choosing a tank?
Measure the available bed space and compare it with the tank’s listed dimensions, allowing for installation and access. The Vigorighter combo is about 50–58 inches long and 19 inches wide; the 45-gallon tank is listed as 57 × 9.5 × 20 inches. Confirm fit before purchasing.
Should I choose a tank with a pump or toolbox?
Choose based on what your setup needs: the Vigorighter combines a tank, toolbox, and pump, while the BreAro listing describes a diesel-focused tank with a pump and filter. A bare tank may suit owners who already have transfer equipment. Compare included components and fuel compatibility before deciding.
Final Words
For a combined tank, toolbox, and pump, the Vigorighter 51-Gallon Combo is the strongest fit, provided its footprint suits your bed and its fuel compatibility meets your needs. For diesel pumping, consider BreAro; for narrow bed space, the 45-gallon tank is 9.5 inches wide. Better Built offers a steel option with baffles and a mounting kit.
Check fit, fuel compatibility, mounting, and transport rules before choosing.
