🛒  Check Price on Amazon →

We researched the Titan Fuel Tanks 7190700 and found it to be a sturdy, high-performance pump ideal for heavy-duty use. Its cast iron housing and hardened steel gears promise durability, and the 15 GPM flow rate is among the highest in its class.

In our evaluation, the GPI M-150S offers a strong balance of performance and affordability. It delivers 15 GPM and features a self-priming design that can run dry without damage, a useful feature for occasional users. The cast iron body with powder coat finish resists corrosion, and the two-year warranty adds reassurance. Owner reviews consistently praise its reliability.

One limitation is that it does not come with a nozzle, so you will need to purchase one separately. We recommend this pump for budget-conscious buyers who still want a durable, high-flow pump. If you prefer a complete kit with hose and nozzle, you may want to look at other options.

• Self-priming and can run dry without damage
• Cast iron body with powder coat finish

🛒  Check Price on Amazon →

We compared the Fill-Rite FR1204H and found it to be a well-built pump that comes as a complete kit with a 12-foot hose and manual nozzle. The cast iron housing and bypass valve enhance safety and longevity. Owner feedback indicates it works reliably for diesel transfer in truck beds. The 12 GPM flow rate is adequate for most needs, though not the fastest.

The main drawback is the lower flow rate compared to 15 GPM models. If you frequently transfer large volumes, a faster pump may be a better choice. We recommend this for users who value a complete, ready-to-use package and don’t need maximum speed.

• Heavy-duty cast iron housing with powder coat
• Built-in bypass valve for safe operation
• Includes 12 ft. hose and manual nozzle

Pros: Includes hose and nozzle for complete setup; Very durable construction
Cons: Lower flow rate than some competitors

4. Kendrick 12V Diesel Fuel Transfer Pump (K12V-15GPM): High Flow

🛒  Check Price on Amazon →

After researching the Kendrick K12V-15GPM, we found it offers a high flow rate of 15 GPM in a lighter aluminum housing. This makes it easier to handle and install. The included strainer and check valve are practical additions. Owner reviews mention it performs well for diesel transfer, though some note the aluminum body may dent more easily than cast iron.

The trade-off for lighter weight is reduced impact resistance. We recommend this pump for users who prioritize portability and flow rate over maximum durability. If you expect rough handling or heavy-duty use, a cast iron pump might be a better investment.

• Aluminum housing for lighter weight
• 15 GPM flow rate for fast transfer
• Includes strainer and check valve

Pros: Lighter than cast iron pumps; High flow rate
Cons: Aluminum may be less durable than cast iron

5. Flojet 12V Fuel Transfer Pump (G57-2): Compact Design

🛒  Check Price on Amazon →

In our evaluation, the Flojet G57-2 is a compact, lightweight pump that is easy to move and store. It is self-priming and can run dry, which adds convenience. However, its flow rate of only 6 GPM is significantly lower than most truck bed pumps, making it slow for large transfers. Owner feedback generally positive for light-duty use, but some report it struggles with thicker diesel in cold weather.

We recommend this pump only for those who need occasional, small-volume transfers and value portability over speed. If you regularly transfer 50+ gallons, look for a higher-flow model.

• Compact and lightweight for easy portability
• Self-priming and can run dry
• Suitable for both diesel and gasoline

Pros: Very portable and easy to store; Self-priming feature
Cons: Low flow rate of 6 GPM

6. Polaris 12V DC Fuel Transfer Pump (2881104): Basic Utility

🛒  Check Price on Amazon →

We researched the Polaris 2881104 and found it to be a budget-friendly option with a plastic housing that keeps weight low. It delivers 8 GPM and comes with long battery leads for convenient hookup. However, owner feedback indicates the plastic components may crack under stress, and the pump is not self-priming, requiring manual priming each time. It also struggles with higher viscosity fuels.

We recommend this pump only for very occasional, light-duty use with clean diesel or gasoline. If you need a reliable pump for regular use, we suggest investing in a more durable model with a metal housing.

• Lightweight plastic housing
• 8 GPM flow rate
• Includes 20 ft. battery leads

Pros: Very affordable; Long battery leads for easy connection
Cons: Plastic housing less durable; Not self-priming

7. Hudson 12V Fuel Transfer Pump (H12V-10GPM): Budget Pick

🛒  Check Price on Amazon →

After comparing the Hudson H12V-10GPM, we found it offers a decent 10 GPM flow rate in an aluminum housing at a low price point. It comes with a strainer and check valve, which are useful. However, owner reviews are mixed, with some users reporting seal failures after a few months of use. The pump also lacks thermal protection, which could be a safety concern during prolonged operation.

We recommend this pump only for users on a tight budget who need a pump for occasional, low-volume transfers. For regular or heavy use, we suggest choosing a more reliable model with better build quality and safety features.

• Aluminum housing for moderate durability
• 10 GPM flow rate
• Includes strainer and check valve

Pros: Reasonable flow rate for the price; Includes basic accessories

Frequently Asked Questions

What is the best power source for a truck bed fuel tank pump?

Most truck bed fuel tank pumps use 12V DC power from the vehicle’s battery, which is convenient and provides sufficient power for typical transfer rates. Some pumps also come with battery clamps for easy connection. For higher flow rates or heavy-duty use, 12V pumps are usually adequate. 110V AC pumps are also available but require a generator or inverter, making them less portable.

Can I use a diesel pump for gasoline?

It depends on the pump’s materials and design. Some pumps are rated for both diesel and gasoline, while others are specifically for diesel due to seal compatibility. Always check the manufacturer’s specifications. Using a diesel-only pump with gasoline can damage seals and create a fire hazard. We recommend choosing a pump explicitly rated for the fuel you intend to use.

How do I install a truck bed fuel tank pump?

Installation typically involves mounting the pump securely in the truck bed, connecting the inlet hose to the tank’s outlet, attaching the outlet hose to the nozzle, and wiring the pump to a 12V power source with proper fusing. Many pumps come with detailed instructions. It’s important to ensure all connections are tight and leak-free, and to use a fuse rated for the pump’s amperage to prevent electrical issues.

What safety features should I look for in a fuel transfer pump?

Key safety features include thermal overload protection to prevent overheating, a check valve to prevent backflow, a bypass valve for pressure relief, and a strainer to filter debris. Additionally, look for pumps with spark-proof motors and grounding capabilities to reduce fire risk. Always follow safety guidelines such as grounding the pump and avoiding operation near ignition sources.

How do I maintain my truck bed fuel pump?

Regular maintenance includes checking for leaks, cleaning or replacing the strainer, inspecting hoses for cracks, and ensuring electrical connections are clean and tight. For pumps with seals, periodic lubrication may be recommended. Store the pump in a dry place when not in use. Following the manufacturer’s maintenance schedule can extend the pump’s life.
