Luney Fuel Transfer Pump USB & AA Battery Powered, 3.2 GPM, 51" Hose with Auto-Stop Nozzle

The Luney Automatic Fuel Transfer Pump is a portable, automatic nozzle pump that moves gasoline, diesel, kerosene or non-potable water at up to 3.2 GPM using USB power or AA batteries.

Compact and adaptable, this battery/USB-powered transfer pump is built for homeowners and professionals who need a fast, spill-reducing way to refill equipment and small tanks. It pairs an auto-stop sensor nozzle with four threaded adapters and a 51-inch hose to fit most North American fuel containers and keep transfers tidy and controlled.

How does the Luney pump prevent spills and overfilling?

The nozzle has an integrated auto-stop sensor that detects tank fullness and cuts the flow automatically, then sounds a 30-second alarm to warn you. This reduces overflow risks and keeps the work area cleaner during routine refueling.

• Auto-stop sensor halts flow when the receiving tank is full
• 30-second audible alert after shutoff to avoid accidental overfill
• Nozzle design minimizes splashing and drips at the fill point

What power options does this pump offer and why does that matter?

It operates from a USB 5V input (>2A) or from AA batteries, giving you a tethered option for continuous use and a cordless option for site flexibility. USB power lets you avoid batteries during long jobs; AA batteries keep you mobile where outlets are unavailable.

• USB 5V input supports extended operation without batteries
• Standard 4×AA battery slot for regular portable use; 2×AA works in emergencies
• Dual power modes allow indoor and remote outdoor refueling

Will this pump fit my fuel cans and vehicles?

The pump ships with four threaded adapters (2.0", 2.1", 2.75" and 3.75") to match most North American tanks and cans. Check your can opening — the hose end is 1.25" (3.2 cm); it won’t seal correctly on openings significantly larger than 1.28".

• Four adapter sizes to cover common gas can necks and tank inlets
• 51-inch hose for comfortable reach when refueling cars, mowers, or equipment
• Not compatible with can openings wider than about 1.28" without modification

What tasks is this pump good for around the house and shop?

This lightweight, easy-to-store unit is useful for filling lawn mowers, generators, outboard tanks, motorcycles, and small machinery. It handles gasoline, diesel, kerosene and non-potable water, making it a versatile tool for maintenance and occasional fuel transfers.

• Refuel lawn equipment, portable generators, boats, and ATVs
• Transfer diesel or kerosene for small machinery service
• Short-term water transfer for non-potable uses (not for drinking water)

Who is this for: The Luney Automatic Fuel Transfer Pump is for homeowners, landscapers, boaters and anyone who needs a safer, faster way to move small quantities of fuel or non-potable water without heavy equipment. It suits users who want both the convenience of plug-in USB operation for longer jobs and the freedom of battery power for remote refueling, plus the spill-reduction of an automatic shutoff nozzle. Note: red fuel canister and batteries are not included; confirm your container neck dimensions before purchase to ensure proper fit.
