BuffVorce FN401 5 GPM Cordless Fuel Transfer Pump with Auto-Stop Nozzle

For drivers, boat owners, and equipment operators who need to transfer fuel without lifting and pouring a heavy can, the BuffVorce FN401 offers a powered alternative with a hand-trigger nozzle and automatic shutoff.

Its cordless design works with DeWalt 20V or Milwaukee 18V lithium-ion slide batteries, and an included 12V outlet adapter provides another power option. The battery is sold separately.

Need to refuel from a utility jug in a garage, driveway, or near a boat? The 51-inch hose helps position the nozzle, while the auto-stop feature signals when the tank is full.

Best use cases

Use the FN401 to transfer gasoline or diesel for cars, motorcycles, trucks, boats, mowers, tractors, trailers, RVs, and other equipment. It is also described for transferring oil or water. The hand trigger gives you control at the nozzle, and automatic shutoff helps manage flow when the tank reaches capacity.

The 51-inch reinforced hose connects the pump to the receiving tank, making the setup useful when the fuel container and fill opening are not side by side. Four container adapters are provided for neck sizes of 2 inches, 2.1 inches, 2.75 inches, and 3.75 inches, helping the pump fit a range of standard plastic utility jugs and fuel cans.

Pros

The pump is rated to transfer up to 5 gallons per minute, giving you a powered option in place of slow manual pouring. Its auto-stop nozzle cuts the flow and sounds a beep when the tank is full, while one-button operation and an LED status indicator keep the basic controls straightforward.

Power flexibility is useful across different settings: use a compatible DeWalt 20V or Milwaukee 18V slide battery for cordless operation, or connect the included 12V outlet adapter for continuous use. The ABS housing, rubber sealing ring, and flexible polyethylene hose are designed for a practical fuel-transfer setup.

Key takeaways

This is a fuel-transfer pump for people who regularly move liquids from a can or utility jug into a vehicle, boat, or piece of equipment. Its defining features are the 5 GPM transfer rate, 51-inch hose, automatic shutoff, and compatibility with specified DeWalt and Milwaukee battery platforms.

Compared with a basic siphon or manual pour spout, the FN401 adds powered transfer and an auto-stop nozzle. That approach is especially useful when you want to operate the nozzle directly and have a compatible battery or access to a 12V outlet.

What to clarify

Which batteries can power the pump? It is designed for DeWalt 20V or Milwaukee 18V lithium-ion slide batteries. The battery is not included, an included 12V outlet adapter offers an alternative power source.

What container neck sizes do the adapters fit? The four adapters correspond to 2-inch, 2.1-inch, 2.75-inch, and 3.75-inch neck sizes.

How does the automatic shutoff work? When the tank is full, the auto-stop nozzle cuts the flow and gives a clear beep. The hand trigger lets you operate the nozzle during transfer.

When it makes sense

It makes sense if you want a powered way to refuel vehicles or equipment from a fuel can and value automatic shutoff, a long hose, and a choice of compatible battery power or a 12V outlet. The combination suits routine refueling around a garage, property, or boat, with the adapters helping match the pump to different utility-jug neck sizes.
