EVIL ENERGY 12V DC 20 GPM Fuel Transfer Pump, Cast Iron Diesel Pump Kit

Q: How do I use this pump to refuel tractors and farm equipment with diesel?

A: The EVIL ENERGY 12V DC 20 GPM Fuel Transfer Pump runs off a 12V DC power source, so you can connect it directly to your farm truck’s or tractor’s 12V battery. No wall outlet needed. Set the cast iron pump next to your fuel drum (the included metal bracket lets you mount it securely), drop the 33 in suction tube into the drum, and run the 13 ft discharge hose with the auto shut-off nozzle to your equipment’s tank. With a flow rate of up to 20 GPM, it’s dramatically faster than hauling fuel cans by hand. Since it’s fully diesel compatible, it’s a natural fit for farm and ag equipment.

Q: Can I refuel construction equipment and generators at a remote job site with no power?

A: Yes. Job sites often have trucks on hand but no grid power, and this 12V fuel transfer pump only needs a 12V source to run. You can hook it up to a work truck’s battery, your generator’s starter battery, or a standalone 12V deep-cycle battery. The cast iron body with electrophoretic coating is built for durability and corrosion resistance in demanding job site conditions. The 13 ft discharge hose gives you flexibility to position the drum and equipment, and the auto shut-off stops fuel flow with a beep alert when the tank is full, helping prevent spills and the safety hazards that come with them.

Q: How do I set it up for everyday refueling in my shop or garage?

A: Power the pump with a 12V battery or a 12V DC power supply rated for the pump’s power draw (most garages run on 120V AC, so a converter is needed). Use the included metal bracket to mount the pump on a drum stand or wall, and the 360° swivel and 90° elbows to keep your hose lines neat, creating a semi-permanent refueling station. Thanks to its universal fit, one setup can serve your pickup, farm equipment, and generator. The electrophoretic-coated body also offers added corrosion resistance in a garage environment.

Q: My equipment yard runs a mix of machines and fuels. Can one pump handle it all?

A: It can. This universal-fit transfer pump is compatible with gasoline, diesel, kerosene, and biodiesel, making it well suited for mixed fleets and equipment. When switching fuels, drain any leftover fuel and flush the lines to avoid cross-contamination (take extra care when switching between biodiesel and regular diesel). The 1/4 HP copper-wound motor and cast iron housing deliver steady, reliable performance, and a max head of 33 ft can push fuel up to elevated tanks. On the intake side, keep the fuel level within the 6.6 ft max suction lift below the pump.

Q: Can I use it to fuel gas-powered equipment like lawn mowers, gas generators, and ATVs?

A: Yes. Unlike our cordless 12 GPM diesel transfer pump, this 12V cast iron pump is gasoline compatible, so you can refuel gas mowers, gas generators, motorcycles, ATVs, and other gas-powered equipment straight from the drum. The auto shut-off nozzle and beep alert help prevent overfilling smaller tanks. Always keep away from open flames and sparks, work in a well-ventilated area, and make sure you’re using regular gasoline. E85 is not compatible.

Q: Where does the 12V power come from when there’s no outlet, and how do I connect it?

A: The pump comes with a 12V DC power cable. Common power options include:

1. Clamping directly to the terminals of a car, truck, or tractor 12V battery.
2. Connecting to a standalone 12V battery.
3. Using a 12V DC power supply in your shop that is rated for the pump’s power draw.

Before connecting, double-check polarity (typically red to positive, black to negative) and follow the user manual for all electrical connections. No modifications to your vehicle’s wiring are required. When you’re finished refueling, switch off and disconnect the pump.

Q: Will the motor burn out during long transfers? Does it need to rest?

A: The pump features built-in thermal overload protection, which helps protect the motor from overheating during operation. Even so, we recommend:

1. Never running the pump dry or with a blocked line. Dry running is one of the fastest ways to damage a pump.
2. During large-volume transfers, checking in periodically: feel the housing for excessive heat and listen for unusual noises.
3. Turning off the pump once refueling is done, rather than leaving it running against a closed nozzle.

Thermal protection is a safety net, not a substitute for proper care.

Q: What fluids should never be pumped with this unit? Is E85 the same as gasoline?

A: This pump is not compatible with water, DEF (diesel exhaust fluid), E85, or corrosive chemicals. Keep in mind: E85 is not the same as regular gasoline. E85 is a high-ethanol fuel blend that can damage seals and metal components, so it should never be run through this pump. Regular gasoline, however, is fully compatible. DEF is a water-based urea solution and should not be pumped either, and the same goes for water and corrosive chemicals. In short, use it only for gasoline, diesel, kerosene, and biodiesel.
