A strong auxiliary fuel tank with a pump combines enough fuel capacity for your workday with a transfer rate and installation style suited to your truck or equipment. For buyers who want an integrated truck-bed toolbox and auxiliary-fueling design, the RDS 90-gallon combo stands out with its listed 15 GPM pump. The lineup also includes smaller RDS aluminum combos and portable polyethylene tanks with 12V pumps, hoses and nozzles.
Those portable models offer capacities from 48 to 58 gallons, but their listings do not establish that they connect to a vehicle’s fuel system as an auxiliary tank. Compare the intended use, pump flow, materials and included fittings before choosing; a transfer tank’s pump does not by itself confirm compatibility with your vehicle or fuel system.
The RDS 90-Gallon Combo is the strongest fit for buyers seeking an auxiliary fuel tank with a pump: its listing describes an aluminum transfer-tank and toolbox combo designed for diesel and other nonflammable liquids, and names a 15 GPM pump. Its 90-gallon capacity is the largest stated among the pump-equipped products here. Choose it if you need the RDS truck-bed combo format and can accommodate its listed 55 x 30 x 23.25-inch dimensions and 152-pound weight; verify your truck fit and installation requirements before buying.

Detailed Reviews: Best Auxiliary Fuel Tank With Pump

#1 · Best Overall
1. RDS 90-Gallon Combo
- Dimensions: 55 x 30 x 23.25 in
- Weight: 152 lb
Best for: High-capacity truck-bed transfer.
Why it ranks #1: Its aluminum tank-and-toolbox design is described for auxiliary fueling, and the listed 15 GPM pump and 90-gallon capacity lead this pump-equipped selection.
A 90-gallon capacity and 15 GPM pump set this RDS combo apart for operators moving substantial diesel supplies to remote equipment. The aluminum tank also incorporates a storage box on top, combining fuel transport and a place for supplies in a single pickup-bed unit.
The 55 x 30 x 23.25-inch aluminum combo carries more fuel than the 60-gallon RDS option, which can reduce how often a work crew needs to replenish its supply. Its listed 15 GPM pump supports faster transfer than an 8 GPM setup, while the top storage box keeps tools alongside the tank. The product is specified for diesel and other nonflammable liquids, so its stated use is fuel transfer to remote or heavy equipment.
- 90-gallon capacity
- 15 GPM pump
- Top-mounted storage box combines fuel and supply storage
- Aluminum tank specified for diesel and other nonflammable liquids
- At 152 pounds empty, it is the heaviest listed RDS combo here.
Skip it if you need a lighter portable tank; the 55.6-pound VEVOR 48-gallon tank is easier to handle by listed weight.
This RDS suits truck owners supplying remote or heavy equipment who prioritize 90 gallons and a 15 GPM pump with integrated storage. Its 55-inch length and 152-pound empty weight call for careful truck-bed planning.

#2 · Best Aluminum Combo
2. RDS 60-Gallon Combo
- Dimensions: 55 x 20 x 23 in
- Weight: 110 lb
Best for: Pickup-bed toolbox and transfer.
Why it ranks #2: The aluminum transfer-tank and toolbox combo is designed for diesel and other nonflammable liquids, with a listed 8 GPM pump and 60-gallon capacity.
The 60-gallon tank pairs an 8 GPM pump with a storage box on top, giving pickup owners a way to carry diesel for remote equipment while keeping supplies in the same unit. Its aluminum construction and fully welded seams make it a practical choice for a truck-bed transfer setup.
The 55 x 20 x 23-inch aluminum unit combines fuel capacity with a top-mounted storage box, so tools and transfer fuel travel together rather than requiring separate containers. Fully welded seams support the tank construction, while heavy-duty aluminum mounting brackets provide a mounting point for installation. The spin collar allows easier pump installation. Its 8 GPM pump suits buyers who value the integrated toolbox and 60-gallon capacity over the higher listed flow rates of some alternatives.
- 60-gallon capacity for diesel and other nonflammable liquids
- Integrated storage box sits above the tank
- 8 GPM pump included
- Heavy-duty aluminum mounting brackets and fully welded seams
- At 110 pounds, the tank adds substantial weight before fuel is loaded.
Skip it if you need faster listed flow; the RDS 90-gallon 15 GPM combo offers more capacity and a higher pump rate.
Choose this RDS combo if your pickup needs 60 gallons of diesel capacity, an 8 GPM pump, and a toolbox in one unit. Its 55-inch length and 110-pound empty weight are important bed-planning considerations.

- Weight: 68.8 lb
- Capacity: 58 gallons
- Material: Aluminum, High Density Polyethylene (HDPE)…
Best for: Outdoor 58-gallon fuel transport.
Why it ranks #3: Its 58-gallon portable tank lists a 13.2 GPM, 12V DC pump and DOT requirements, making it a high-flow option, though auxiliary-system fit is not specified.
A stated real capacity of 58 gallons gives this CAMMOO portable tank substantial fuel storage, while its 13.2 GPM rating enables rapid transfer through the 12V DC system. The flame-retardant LLDPE and HDPE construction is specified for outdoor exposure, including UV, rain, snow, wear, and corrosion resistance.
The 58-gallon capacity helps carry a larger fuel reserve, and the 13.2 GPM pump rating supports a brisk transfer workflow.

#4 · Toolbox Combo
4. BLACKHORSE-RACING 51-Gallon Combo
- Capacity: 51 gallons
- Material: Aluminum
Best for: Locked black aluminum combo.
Why it ranks #4: This 51-gallon aluminum tank combines a toolbox with a listed 10 GPM 12V pump, automatic nozzle and 13.1-foot hose.
A 51-gallon black aluminum tank with a double lock and keys protects the pump and supplies while carrying fuel for transfer. Its 10 GPM, 12V DC pump, automatic nozzle, and 13.1-foot hose give buyers a ready-to-use refueling arrangement without separating the toolbox from the tank.
The 12V DC pump is rated at 10 GPM and comes with an automatic refueling nozzle and 13.1-foot hose, giving operators a defined setup for moving fuel from the 51-gallon tank. Black aluminum is described as rust- and corrosion-resistant, a useful material property for a tank exposed to changing conditions. A double lock and keys protect the internal pump and supplies, while the toolbox-combo format keeps storage associated with the fuel unit.
- 51-gallon capacity
- 10 GPM, 12V DC pump
- Automatic refueling nozzle and 13.1-foot hose included
- Double lock and keys protect pump and supplies
- The package does not contain a filter.
Skip it if you require an included filter; the VEVOR 48-gallon portable diesel tank lists a steel-wire-inlaid hose.

#5 · Longest Listed Hose
5. Wolive 50-Gallon Tank
- Dimensions: 20"W x 23"H
- Weight: 67 lb
- Capacity: 50 gallons
- Material: High Density Polyethylene (HDPE)
Best for: Large portable diesel supply.
Why it ranks #5: The 50-gallon HDPE tank is specified for diesel and lists a 12V pump, 11.9 GPM flow rate and 15-foot rubber hose.
The 50-gallon HDPE tank combines a 12V electric pump with an 11.9 GPM flow rate, enabling portable diesel transfer without a truck-bed toolbox combo. Its 15-foot rubber hose gives operators reach between the tank and fueling point, while the lid helps shield stored fuel from rainwater intrusion.
High-density polyethylene is specified for the tank body, which is described as helping prevent leaking and deformation. The solid lid protects against rainwater intrusion, a practical consideration for outdoor transport and storage. For dispensing, the 12V electric pump is paired with an 11.9 GPM flow rate and a 15-foot rubber hose, giving more hose reach than a shorter setup. At 67 pounds and 20 inches wide, the tank has defined handling and space requirements.
- 50-gallon capacity for diesel transport
- 12V electric pump rated at 11.9 GPM
- 15-foot rubber hose
- HDPE body and solid lid protect against stated outdoor concerns
- The listed fuel use is diesel, limiting its stated application.
Skip it if you need an integrated toolbox or a listed gasoline option; the VEVOR 48-gallon tank is specified for diesel and gasoline.
This Wolive tank fits buyers needing 50 gallons of portable diesel with a 15-foot hose and 12V pump. Its 20-inch width and 67-pound weight matter for transport, and its listed use is diesel.

6. VEVOR 48-Gallon Red Tank
- Dimensions: 24.8"W x 23"H
- Weight: 55.6 lb
- Capacity: 48 gallons
- Material: Polyethylene (PE)
Best for: Portable diesel and gasoline refueling.
Why it ranks #6: This 48-gallon polyethylene tank lists a 10.6 GPM 12V pump, 13.1-foot hose and auto-fueling nozzle, but its listing does not establish vehicle auxiliary-system connection.
A 48-gallon polyethylene tank supports both diesel and gasoline transfer, making the VEVOR a versatile portable option for operators handling either listed fuel. Its 12V electric pump is rated at 10.6 GPM and pairs with a 13.1-foot hose and automatic fueling nozzle for a ready refueling workflow.
The 12V pump's 10.6 GPM flow rate works with the automatic nozzle and 13.1-foot hose to move fuel from the portable tank to equipment. Polyethylene construction is described as resisting UV radiation and changing weather conditions, which supports outdoor transport use. A lockable upper lid with a copper lock secures the tank. At 48 gallons and 24.8 inches wide, it trades a more compact footprint for less capacity than larger listed portable tanks.
- Specified for diesel and gasoline
- 10.6 GPM 12V electric transfer pump
- 13.1-foot hose and automatic fueling nozzle
- Lockable lid with copper lock
- Its 48-gallon capacity is smaller than the listed 50- and 58-gallon portable options.
Skip it if you need more than 48 gallons in a portable tank; the CAMMOO 58-gallon portable tank offers greater listed capacity.
Choose this VEVOR for portable diesel or gasoline refueling with an automatic nozzle, 13.1-foot hose, and lockable lid. Its 48-gallon capacity and 24.8-inch width should suit your transport space.

- Dimensions: 24.8"W x 23"H

Best for: Portable diesel tank with gauge.
Why it ranks #7: Its 48-gallon polyethylene tank lists a 10.6 GPM 12V pump and an eight-level fuel gauge, but no vehicle auxiliary connection is specified.
An 8-level fuel gauge gives the VEVOR 48-gallon diesel tank a clear way to monitor remaining supply, while its 10.6 GPM, 12V pump supports transfer on the move. A lockable lid and steel-wire-inlaid rubber hose add practical security and hose durability details to this portable setup.
The 12V pump delivers fuel at a listed 10.6 gallons per minute, while the 8-level gauge helps track the tank's remaining diesel during use. Its steel-wire-inlaid rubber delivery hose is described as flexible and resistant to damage, supporting repeated handling. Polyethylene construction is specified as UV-resistant and suited to changing weather, and a copper-lockable upper lid helps secure the tank. The 48-gallon capacity and 24.8-inch width define its storage footprint.
- 48-gallon diesel capacity
- 12V pump rated at 10.6 GPM
- 8-level fuel gauge
- Steel-wire-inlaid rubber hose and lockable upper lid
- The listed fuel application is diesel, not gasoline.
Skip it if you need a listed gasoline-transfer option; the VEVOR 48-gallon 10.6 GPM tank with automatic nozzle specifies diesel and gasoline.
This VEVOR fits diesel users who want a portable 48-gallon tank, visible gauge levels, and a 10.6 GPM pump. Its 24.8-inch width and diesel-only stated application are relevant fit boundaries.

8. RDS 60-Gallon Tank Toolbox
- Weight: 16 oz
- Capacity: 60 gallons
- Material: Alloy Steel, Aluminum, Stainless Steel
Best for: Auxiliary tank and toolbox setup.
Why it ranks #8: This 60-gallon RDS toolbox combo is described as auxiliary-capable, but the supplied listing does not specify an included pump, so it misses the pump requirement.
The 60-gallon RDS tank combines an auxiliary-fuel role with a toolbox, enabling truck owners to carry fuel and supplies in a single unit. Its listed dimensions are 55 x 20 x 19.5 inches, and the product description notes that RDS auxiliary tanks can connect to a vehicle fuel tank for gravity feed.
The 60-gallon capacity and truck compatibility make this RDS unit relevant to pickup owners needing added fuel storage. Its 55 x 20 x 19.5-inch dimensions provide a concrete footprint for bed planning, while the toolbox-combo title indicates a storage function alongside the tank. The description explains that RDS auxiliary tanks connect to a vehicle fuel tank and diesel can gravity-feed from the bottom; an optional diesel install kit is sold separately, so installation planning matters.
- 60-gallon capacity
- Truck-compatible listing
- Toolbox and auxiliary fuel tank combo
- Description specifies gravity feed through an optional diesel install kit
- The optional diesel install kit is sold separately.
Skip it if you want a pump and hose specified in the product details; the VEVOR 48-gallon tank lists a 12V pump and 13.1-foot hose.
Consider this RDS for a truck owner prioritizing 60-gallon auxiliary storage and a toolbox combo. Its described gravity-feed connection requires planning around the separately sold diesel install kit.

View on AmazonAuxiliary feed and transfer pumping are not the same
A transfer pump moves fuel through a hose, while an auxiliary connection to a vehicle’s fuel system is a separate fitment question. The RDS descriptions explicitly say most RDS transfer tanks can provide auxiliary fueling and that diesel may gravity-feed from the tank bottom; they also mention optional diesel install kits, sold separately. By contrast, the portable Wolive, VEVOR, CAMMOO and BLACKHORSE-RACING listings describe powered refueling, but the supplied details do not confirm a connection to a truck’s fuel tank.
Do not assume that a pump-equipped tank can feed your vehicle automatically, or that a hose and nozzle replace an installation kit. Confirm the vehicle’s fuel-system compatibility, the required fittings and applicable installation rules before relying on auxiliary feed.
This distinction matters especially if you need to extend driving range rather than refuel equipment from the truck bed.
Check fuel compatibility before filling
Do not treat every tank in this roundup as suitable for every fuel: the stated fuel-use claims differ. The RDS combo descriptions specify diesel and other nonflammable liquids, while the Wolive listing identifies diesel use. The VEVOR and CAMMOO titles and descriptions focus on diesel; the BLACKHORSE-RACING title says gasoline and diesel.
Those product statements do not establish that every pump, hose, seal or vehicle installation is compatible with a given fuel. In particular, a tank’s material alone is not proof of fuel-system suitability.
Match the complete assembly—including pump and delivery components—to the fuel you intend to carry, and follow the product instructions and applicable transport requirements. The VEVOR orange-tank listing also warns never to refuel hot or burning devices because of explosive-flame risk. Treat safe transfer practices as essential, not as a feature implied by a tank’s capacity or flow rate.
How to Choose an Auxiliary Fuel Tank With Pump
Capacity and truck-bed fit
Choose a capacity that meets your fuel needs without exceeding the space or load your vehicle can handle. The pump-equipped choices range from 48 gallons for the VEVOR tanks to 90 gallons for the RDS 90-Gallon Combo; other options include 50, 51, 58 and 60 gallons. Listed dimensions vary too: the RDS 90-Gallon Combo measures 55 x 30 x 23.25 inches and weighs 152 pounds, while the RDS 60-Gallon Combo measures 55 x 20 x 23 inches and weighs 110 pounds.
The larger RDS option suits buyers prioritizing fewer refills and who can confirm the bed fit and load limits. Buyers with tighter space needs should compare the smaller capacities and actual dimensions rather than assume gallons alone predict fit.
Pump flow and included transfer gear
Look at both the stated flow rate and the equipment included to make sure the setup suits your transfer routine. Listed pump rates range from 8 GPM on the RDS 60-Gallon Combo to 15 GPM on the RDS 90-Gallon Combo; the portable models list 10, 10.6, 11.9 or 13.2 GPM. The BLACKHORSE-RACING combo includes an automatic nozzle and 13.1-foot hose, and the Wolive listing specifies a 15-foot rubber hose.
The VEVOR red tank lists a 13.1-foot hose and auto-fueling nozzle. A buyer moving fuel frequently may favor the higher stated flow, while someone needing a particular hose reach should compare listed lengths.
Treat advertised flow as a product specification, not a guarantee of real-world delivery under every setup.
Tank material and intended format
Match the tank construction and format to how you plan to carry and use fuel. RDS’s pump-equipped combos are aluminum, measure 55 inches long and include a toolbox; portable alternatives use polyethylene or listed blends. The VEVOR tanks are polyethylene and weigh 55.6 pounds, while the CAMMOO tank lists HDPE and LLDPE alongside aluminum and weighs 68.8 pounds.
The BLACKHORSE-RACING combo is black aluminum and includes a toolbox. A buyer seeking an integrated truck-bed storage box may prefer an RDS or BLACKHORSE-RACING combo.
Buyers who want a portable tank format may consider the polyethylene models, while checking each product’s stated fuel use, dimensions and installation needs. Material descriptions alone do not confirm compatibility with a particular fuel or vehicle.
Which auxiliary fuel tank with pump should you choose?
For a truck-bed combo explicitly described as auxiliary-capable and equipped with a pump, choose the RDS 90-Gallon Combo if its 55 x 30-inch footprint and 152-pound weight suit your setup. The RDS 60-Gallon Combo is the more compact listed RDS pump option, with a 60-gallon capacity and 8 GPM pump. If you want a portable tank and prioritize stated flow, the CAMMOO 58-Gallon Tank lists 13.2 GPM; its supplied details do not confirm a vehicle auxiliary connection.
The BLACKHORSE-RACING 51-Gallon Combo adds a toolbox, automatic nozzle and 13.1-foot hose. For diesel-focused portable choices, compare Wolive’s 15-foot hose with VEVOR’s 48-gallon tanks.
The RDS 60-Gallon Tank Toolbox is the one to avoid when an included pump is essential: none is listed.

Frequently Asked Questions
Will an auxiliary tank gravity-feed into my specific truck’s fuel system?
Do not assume it will; compatibility depends on your truck and tank setup. The listings do not establish that every tank can gravity-feed into a particular vehicle’s fuel system. Check your truck manufacturer’s requirements and the tank’s installation instructions, and have a qualified installer confirm compatibility before connecting a tank.
What approvals and installation requirements apply to carrying a transfer tank on my vehicle?
Requirements depend on your vehicle, location, tank, and intended use. These listings alone do not establish which approvals or installation rules apply. Before purchase or installation, check applicable local and transport regulations, your vehicle manufacturer’s guidance, and the tank maker’s instructions; consult a qualified installer if requirements are unclear.
Can the listed pump and tank safely handle the fuel type I plan to transfer?
Only if the specific tank and pump are rated for that fuel; do not infer compatibility from a flow rate or a general product title. The RDS 90-gallon combo is described for diesel and other nonflammable liquids, while other listings mention diesel or gasoline. Verify both components’ instructions before use.
How should I choose between the listed tank capacities?
Start with the amount of fuel you need and the space and weight your vehicle can accommodate. The pump-equipped options range from the 48-gallon VEVOR tanks to the 90-gallon RDS combo; the RDS 90-gallon listing specifies dimensions of 55 x 30 x 23.25 inches and a weight of 152 pounds.
Which listed option includes a pump, and which does not?
The RDS 60- and 90-gallon combos, the 51-gallon combo, the portable 50-gallon tank, the VEVOR 48-gallon pump tank, and CAMMOO’s 58-gallon tank list pumps. The RDS 60-gallon toolbox tank does not list an included pump, so it is not the choice when one is essential.
Final Words
For a truck-bed combo with the largest stated capacity among the pump-equipped options, consider the RDS 90-Gallon Combo if its dimensions and weight suit your setup. The RDS 60-Gallon Combo is a more compact listed pump option. For portable tanks, compare the stated capacity, flow, and hose details, while confirming fuel compatibility.
Before choosing any product, verify vehicle fit, installation rules, and whether the tank can connect as you intend.
