EVIL ENERGY Fuel Transfer Pump Battery Powered, 12 GPM Diesel Kerosene Oil

Q: How do I refuel my tractor with this pump out in the field with no power source?

A: This pump is completely cordless and comes standard with a 4.0Ah battery and charger, so there’s no need for an outlet or a hookup to your tractor’s battery. Set the pump right next to your diesel drum, connect the inlet hose (with mesh intake strainer), the outlet hose, and the auto shut-off nozzle, then install a fully charged battery and you’re ready to go. The built-in carrying handle makes it easy to move between rows and across uneven ground. For faster priming, set the drum slightly higher than the pump so gravity can help with the initial draw. If the drum sits below the pump, keep the fuel level within the 10 ft max suction lift.

Q: My diesel pickup ran out of fuel at a remote job site. Can I refuel it myself from a diesel drum?

A: Absolutely. Off-grid diesel refueling far from power outlets and fuel stations is exactly what this pump was built for. The reinforced hoses move diesel from the drum in your truck bed straight into your pickup’s tank, and with a flow rate of up to 12 GPM, a typical diesel pickup can be filled in just a few minutes. When the tank is full, the auto shut-off stops the flow and sounds a beeper alert to help prevent overfilling. There’s no need to tap into your vehicle’s wiring, and one person can handle the job. Please stay with the pump during transfer. Note: this pump is not for gasoline, so it is not suitable for gas-powered trucks.

Q: Can I use it to top off my diesel backup generator from stored fuel during a power outage?

A: It’s a great fit. Diesel backup generators are often located in utility rooms, garages, or outdoors, not always near a working outlet. This cordless, portable pump lets you transfer diesel from your storage drums into the generator’s tank. Dual automatic shut-off stops the flow when the receiving tank is full or the source fuel level runs low, helping prevent overfilling and running dry, while the audible beep alerts you even in a noisy environment. We recommend staying with the pump while refueling and keeping some battery charge in reserve.

Q: How do I use this pump to refuel a diesel boat at the dock or on board?

A: You can transfer diesel from a drum on the dock or deck into your boat’s fuel tank. Just be sure to check two height limits first:

• Max suction lift: 10 ft (vertical distance from the fuel in the drum up to the pump)
• Max lift: 20 ft (how high the pump can push fuel up to the boat’s tank)

Most small diesel fishing boats and pleasure craft fall well within this range. The reinforced hoses, hose clamps, metal connectors, and sealing components help reduce leaks in a marine environment.

Q: Besides diesel, can it transfer machine oil or transformer oil for heavy equipment?

A: Yes. This pump is compatible with four fluids: diesel, kerosene, machine oil, and transformer oil, which makes it a handy tool for machine oil changes and general fluid transfer during equipment maintenance. The mesh intake strainer helps screen out particles to protect both your equipment and the pump. When switching between fluids, be sure to fully drain any leftover fluid first to avoid cross-contamination. Not for gasoline, water, or ethanol.

Q: I need to refuel several machines in one day. Will one battery be enough?

A: On a full charge, a single battery can transfer up to about 336 gallons (enough to fill seven 48-gallon tractor tanks), though actual capacity varies with operating conditions such as lift height, fluid viscosity, and temperature. For heavy workloads, we recommend:

1. Keeping a spare battery on hand to rotate.
2. Following the operating cycle: 15 minutes of rest after every 30 minutes of continuous use. Swapping batteries during the rest period keeps things moving efficiently.
3. Planning your charging schedule ahead of time based on the total tank capacity of your equipment.

Q: My fuel drum is on the ground, but the equipment is on a slope or a second level. Are 20 ft of lift and 10 ft of suction lift enough?

A: Suction lift (10 ft) is how far below the pump it can draw fuel up from, so keep the drum low and the pump close to it. Max lift (20 ft) is how high the pump can push fuel from the outlet up to the receiving equipment. As long as the fill point is no more than 20 ft above the pump and the drum is no more than 10 ft below it, you’re covered. If your setup exceeds these limits, move the pump to a better position. Pushing beyond the rated range will cause flow to drop off sharply.

Q: Does cold weather affect battery life and flow rate? How should I plan for winter?

A: Cold temperatures reduce battery capacity and make diesel thicker, so the amount you can transfer per charge will vary. For winter use, we recommend:

1. Charging batteries indoors where it’s warm and installing them right before use.
2. Expecting flow to run slightly below 12 GPM as diesel thickens. This is normal.
3. Sticking to the rest cycle. Even in cold weather, the battery still needs a break from continuous full-load use.
4. Checking the forecast and your equipment’s fuel levels before you start, and keeping at least 20% battery capacity in reserve.
