DEMAKIMI Cordless Fuel Transfer Pump 4.5 GPM (Bare Tool) — 51in PVC Hose, Battery Compatible

The DEMAKIMI 4.5GPM Cordless Fuel Transfer Pump is a battery-powered, high-flow transfer tool that quickly moves gasoline, diesel, light oils and non-potable water using DeWalt 20V or Milwaukee 18V batteries (bare tool).

This compact, handheld pump is built for people who need fast, portable fueling without running cords or generators. Designed to accept common U.S. gas can sizes and to withstand jobsite conditions, it pairs with popular power-tool batteries so you can tap existing battery packs and avoid extra chargers. The unit is ETL- and FCC-certified and ships with multiple adapters plus a reinforced 51-inch PVC hose.

How fast will this pump refill a tank?

With a maximum output of 4.5 gallons per minute (GPM), the DEMAKIMI pump shortens refueling time significantly compared with small manual pumps. Typical use cases like topping off a lawn tractor or filling a 25-gallon boat tank are completed in minutes rather than hours.

• Top rate: 4.5 GPM for rapid transfers
• 25-gallon tank fills in roughly 5–6 minutes
• Three adjustable flow settings for controlled filling

Which batteries and fuels are compatible?

This tool is sold as a bare tool and accepts DeWalt 20V batteries (including POWERSTACK) and Milwaukee 18V batteries, so you can use the battery systems you already own. It is suitable for gasoline, diesel, light oils and non-potable water — not intended for drinking water or corrosive chemicals.

• No charger included — accepts DeWalt 20V or Milwaukee 18V packs
• Works with gasoline, diesel, and light oils
• Not for potable water or aggressive solvents

Will it fit my gas cans and hold up on a worksite?

The pump arrives with a 1.1-inch suction inlet and multiple adapters to fit most American gas cans, removing the guesswork about spout sizes. The 51" reinforced PVC hose resists kinks, UV damage, and temperature extremes, making it suitable for outdoor and mobile use.

• Includes adapters: 2.0", 2.1", 2.75", 3.75" plus a universal adapter
• 51" reinforced PVC hose for durability and flexibility
• Designed to resist leaks, kinks, and weather exposure

What safety and quality assurances come with the pump?

• ETL and FCC certified for safety and electromagnetic compliance
• High-grade materials and three-stage quality checks
• Designed to meet typical jobsite durability expectations
