1. RDS Manufacturing 30-Gallon Aluminum Fuel Tank with 12V Pump: Best Overall
The RDS 30-gallon aluminum tank is a top contender for pickup owners who need a balance of capacity and portability. In our research, owners consistently praised the pump’s consistent 10 GPM flow and the automatic shut-off nozzle that prevents spills. The aluminum body is significantly lighter than steel alternatives, making it easier to handle during installation and removal. The tank meets DOT and EPA requirements, and the anti-siphon valve adds an extra layer of security against theft.
However, aluminum is more prone to denting than steel, so rough treatment on a job site could leave cosmetic marks. We recommend this tank for users who prioritize weight savings and corrosion resistance. If you frequently haul heavy loads and need maximum impact resistance, a steel tank might be a better fit.
- Rugged aluminum construction resists corrosion and is lighter than steel.
- Integrated 12V pump delivers up to 10 gallons per minute for fast transfers.
- Includes automatic shut-off nozzle and anti-siphon valve for safety.
Pros: Lightweight yet durable aluminum build.; High-flow pump with reliable automatic shut-off.
Cons: Aluminum can dent if struck hard.
2. Northern Tool 50-Gallon Steel Transfer Tank with 12V Pump: Runner Up
The Northern Tool 50-gallon steel tank is built for serious users who need maximum capacity and durability. The heavy-gauge steel and powder coat finish withstand rough handling and weather. In owner feedback, the tank’s robust construction and stable mounting brackets were frequently highlighted. The 12V pump operates reliably, though at 7 GPM it is slower than some competitors. The manual nozzle requires attention to avoid spills, but the large fill opening makes refueling the tank itself quick.
The main drawback is weight: a full 50 gallons of diesel adds over 350 pounds plus the tank itself, which can push smaller pickups over payload limits. We recommend this tank for full-size trucks with sufficient payload capacity. If you have a midsize truck, consider a smaller aluminum model.
- Heavy-duty steel tank with powder-coated finish for long life.
- 12V pump with 7 GPM flow and manual nozzle.
- Large fill opening and built-in sight gauge for easy monitoring.
Pros: Extremely durable steel construction.; Generous 50-gallon capacity for extended work.
Cons: Heavy when full, may exceed payload on smaller pickups.
3. Dee Zee 30-Gallon Diamond Plate Steel Transfer Tank: Best Steel Tank
The Dee Zee diamond plate tank combines classic looks with solid functionality. The steel construction and powder coating provide excellent durability, and the diamond plate pattern adds a rugged aesthetic that many truck owners appreciate. In our evaluation, the manual pump is reliable and simple, requiring no electrical connections. The 5 GPM flow rate is adequate for occasional use, and the lockable cap adds security. The tank meets DOT specifications and includes an anti-siphon valve.
However, manual pumping becomes tiresome when transferring large volumes of fuel. This tank is best suited for users who only need to fuel a few pieces of equipment occasionally. If you transfer fuel daily or in large quantities, a 12V pump model will save significant time and effort.
- Attractive diamond plate steel finish with durable powder coat.
- Manual rotary pump delivers 5 GPM, no electrical hookup needed.
- Includes lockable cap and anti-siphon device.
Pros: Stylish appearance that complements truck bed aesthetics.; Simple manual operation with no battery drain.
Cons: Manual pumping is labor-intensive for large transfers.
4. Westward 25-Gallon Polyethylene Transfer Tank: Best Budget Pick
The Westward 25-gallon polyethylene tank is an economical solution for light-duty fuel transport. Its plastic body is lightweight and immune to rust, making it easy to move around. In owner reviews, the tank was appreciated for its low price and adequate performance for occasional use. The hand pump is simple but slow, delivering about 3 GPM. The tank includes a vented cap and a basic hose.
On the downside, polyethylene is not as rugged as steel or aluminum. Several users reported cracks after rough handling or exposure to extreme cold. We recommend this tank only for light, infrequent use and for users who store it in a protected environment. If you need a tank for regular heavy use, invest in a metal model.
- Lightweight and rust-proof polyethylene construction.
- Low cost makes it accessible for budget-conscious buyers.
- Hand pump with hose and manual nozzle.
Pros: Very affordable entry-level option.; Will not rust or corrode.
Cons: Plastic is less durable than metal; can crack if dropped.; Slow manual pump is best for small jobs.
5. Transfer Flow 40-Gallon Auxiliary Fuel Tank System: Best Integrated System
The Transfer Flow 40-gallon system is for those who want a permanent, integrated solution. Rather than a standalone tank with a pump, this system can replace the OEM tank or be mounted in the bed and plumbed to the truck’s fuel system. In our research, owners praised the increased range and the convenience of not having to manually transfer fuel. The system includes a sending unit, gauge, and all necessary hardware. It meets CARB and EPA requirements, ensuring legality in all states.
However, installation is not a simple bolt-on job. It involves fuel line modifications and electrical connections, so professional installation is often recommended. The cost is also higher than a basic transfer tank. This product is best for long-haul drivers or those who want a permanent range extension. If you need a portable solution for fueling equipment, a standard transfer tank is more practical.
- Designed to replace the factory fuel tank or mount in bed as auxiliary.
- Gravity-fed system transfers fuel directly to the truck's tank.
- Includes sending unit and fuel gauge; meets CARB and EPA standards.
Pros: Seamless integration with truck's fuel system.; High safety standards with certified components.
Cons: Installation is complex; may require professional help.; Higher upfront cost compared to standalone tanks.
6. Titan Fuel Tanks 30-Gallon Diesel Transfer Tank: Best with 12V Pump
Titan Fuel Tanks offers a well-rounded 30-gallon steel tank with a capable 12V pump. The LED fuel gauge is a standout feature, providing clear level indication even in low light. In our evaluation, the pump delivered a consistent 8 GPM and was noted for being quieter than many competitors. The automatic shut-off nozzle helps prevent overfills, and the anti-siphon valve adds security. The steel body is durable and the powder coating resists chips and corrosion.
The primary downside is weight: a full tank adds roughly 250 pounds of fuel plus the tank itself. This can affect payload and fuel economy. We recommend this tank for users who want a reliable pump and gauge in a durable steel package. If weight is a concern, consider an aluminum model.
- Built-in 12V pump with 8 GPM flow and LED fuel gauge.
- Rugged steel construction with black powder coat finish.
- Includes automatic shut-off nozzle and anti-siphon valve.
Pros: LED gauge makes monitoring fuel level easy.; Pump is quiet and reliable according to owner feedback.
Cons: Steel is heavy; adds significant weight to the truck.
7. Fuel Transfer Tank 14-Gallon Portable Diesel Can: Best Compact Option
This 14-gallon portable diesel can is the smallest option in our guide, designed for those who need occasional fuel transport for small equipment or emergency reserves. Its polyethylene body is lightweight and rust-proof, and the rotary hand pump is simple to operate. In owner feedback, the tank was valued for its portability and low cost. It can be stored easily when not in use.
However, the small capacity and slow pump make it impractical for frequent or large-scale fueling. The plastic construction is less durable than metal, and the pump may wear out with heavy use. We recommend this tank only for users with minimal fuel needs, such as fueling a lawn tractor or generator. For regular job site use, a larger tank with a 12V pump is a better investment.
- Compact size fits easily in small truck beds or SUVs.
- Rotary hand pump with flexible hose.
- Lightweight and portable at only 12 lbs empty.
Pros: Very portable and easy to store.; Good for emergency fuel or small engines.
Cons: Very slow pumping; only 2 GPM.; Small capacity limits use to light tasks.
Frequently Asked Questions
What size fuel transfer tank do I need for my pickup?
The size depends on your truck’s payload capacity and how much fuel you need to carry. A 30-gallon tank is a good balance for most full-size pickups, adding about 240 pounds of diesel. For smaller trucks, 20 to 25 gallons is safer. Always check your truck’s payload rating and subtract the weight of the tank and fuel.
Are fuel transfer tanks legal to carry in a pickup bed?
Yes, as long as they meet DOT and EPA regulations. Most tanks sold for this purpose are certified. Ensure the tank is properly secured and that the fuel is only for off-road use or your own equipment. Some states have additional restrictions, so check local laws.
Should I choose a manual or 12V pump?
A 12V pump is much faster and easier for regular use, but it requires a battery connection and can drain the battery if used extensively. Manual pumps are simpler, cheaper, and don’t need power, but they are slower and require physical effort. Choose based on how often you transfer fuel.
Can I use a fuel transfer tank for gasoline?
Most transfer tanks are designed for diesel only. Gasoline is more volatile and requires different safety certifications. Using a diesel tank for gasoline can be dangerous and may void warranties. Always check the manufacturer’s specifications.
How do I secure a fuel transfer tank in my pickup bed?
Most tanks come with mounting brackets or straps that bolt to the bed. Use the provided hardware or aftermarket tie-downs. Ensure the tank cannot shift during driving. Some users add a rubber mat underneath to prevent scratching and sliding.
