DEMAKIMI Cordless Fuel Transfer Pump 4.5 GPM (Bare Tool) — 51" Reinforced PVC Hose, 3-Speed

The DEMAKIMI 4.5GPM Cordless Fuel Transfer Pump is a battery-powered, high-flow fluid transfer tool designed to move gasoline, diesel, light oils and non-potable water quickly and safely using DeWalt 20V or Milwaukee 18V batteries.

This compact, bare-tool pump pairs with your existing DeWalt 20V (including POWERSTACK) or Milwaukee 18V batteries to deliver fast, portable refueling and fluid handling without a dedicated power source. Built for workshops, farms, marinas and mobile users, it combines a reinforced 51-inch PVC hose, multiple gas-can adapters, and three selectable flow speeds so you can refuel small engines or drain tanks efficiently while avoiding spills.

How fast will this pump refill my equipment?

At its highest setting the DEMAKIMI pump moves up to 4.5 gallons per minute, significantly reducing the time spent waiting for tanks to fill. That rate typically fills a 25‑gallon tank in about five to six minutes, freeing you to keep working.

• Top flow: 4.5 GPM for fast refueling
• Three adjustable speeds for control and precision
• Ideal for boats, tractors, SUVs and large cans

Will it work with the gas cans and batteries I already own?

Yes — the pump accepts DeWalt 20V (including POWERSTACK) and Milwaukee 18V battery platforms, so no extra power source is required. The suction inlet is upgraded to 1.1" and the kit includes four common gas‑can adapters plus a universal adapter to fit most U.S. containers.

• Compatible with DeWalt 20V and Milwaukee 18V batteries
• Includes adapters: 2.0", 2.1", 2.75", 3.75" and a universal fit
• Works with standard American gas-can openings without modification

How durable and safe is the pump for outdoor use?

The pump uses a reinforced PVC hose that resists kinks, cracking, and chemical degradation, so it stands up to tough jobsite conditions and temperature swings. In addition, the unit carries ETL and FCC certifications, reflecting component testing and electromagnetic compliance for safer operation.

• 51" reinforced PVC hose resists kinks, rust, and leaks
• Rated for gasoline, diesel, light oils, and non-potable water
• ETL and FCC certified with multi-stage factory testing

How do the adjustable flow settings help prevent spills?

The three flow rates let you tailor speed to the task: use a low setting for topping off small tanks and a high rate for bulk transfers. This control reduces splashing and overfills while making transfers faster when precision is less important.

• Low speed for small tanks and precision filling
• Medium speed for balanced control and speed
• High speed for rapid transfers when time matters

Who is this for? The DEMAKIMI cordless fuel pump is aimed at professionals and hobbyists who need fast, portable fluid transfer without a tethered power supply: landscapers, ranchers, mechanics, marina operators, and anyone maintaining vehicles or equipment off-grid. It’s also a practical choice for homeowners who want a safer, quicker way to top off lawn mowers, motorcycles, ATVs and portable generators using batteries they already own. Note that this listing is for the bare tool; batteries and chargers are sold separately.
