Luney Automatic Fuel Transfer Pump USB or AA Battery, 3.2 GPM, 51" Hose with Auto-Stop

The Luney Automatic Fuel Transfer Pump is a portable, USB or battery-powered pump that moves up to 3.2 GPM and automatically stops to prevent overfill.

Compact and easy to carry, this Luney pump is designed for quick, controlled transfers of gasoline, diesel, kerosene and even non-potable water. It can run from a USB 5V source or from AA batteries, comes with four adapter sizes to fit most North American cans, and includes a 51-inch hose so you can refuel equipment at a distance without lifting heavy containers.

How fast and reliable is the Luney pump for routine refueling?

The unit delivers up to 3.2 gallons per minute when supplied with adequate power, making it suitable for topping off vehicles and small machinery quickly. Its motor and flow path are optimized for smooth delivery without frequent clogging or sputtering.

• Maximum flow: 3.2 GPM with sufficient power input
• Works with gasoline, diesel, kerosene, and non-potable water
• Stable, continuous pumping for fast transfers

What power options does the pump offer and when should I use each?

Luney provides two convenient power modes: USB power (DC 5V, ≥2A) for corded operation, and battery power using 4 AA cells for cordless use, with 2 AA as an emergency option. Use USB when you have shore power or a power bank; switch to batteries when you need portability away from outlets.

• USB mode: plug into a 5V/≥2A supply—no batteries required
• Battery mode: normally 4 AA for best performance; 2 AA can be used in emergencies
• Portable for field use; corded for longer, steady operation

Does it help prevent spills and overfills?

Yes — the nozzle includes an auto-stop sensor that detects a full tank and cuts flow, then emits a 30-second alert to reduce the chance of fuel spill or overflow. This feature is designed to keep refueling cleaner and safer without constant monitoring.

• Auto-stop sensor halts fuel flow when tank is full
• 30-second alarm notifies you after automatic shutoff
• Reduces spill risk and improves job-site cleanliness

What adapters and hose options come with the kit?

The pump kit includes four threaded adapters—2.0", 2.1", 2.75" and 3.75"—to fit most North American fuel openings, plus a flexible 51-inch hose to reach recessed tanks or distant equipment. Check the adapter and hose end sizes before purchase to ensure compatibility with your cans.

• Four adapter sizes to match common can openings
• 51" hose for extended reach and easier positioning
• Tube end diameter: 1.25" (3.2 cm); not for openings larger than 1.28"

Who this is for: The Luney Automatic Fuel Transfer Pump is aimed at homeowners, landscapers, boaters, and small-fleet operators who need a fast, portable way to refill equipment without lifting heavy cans. It suits anyone who values spill reduction and flexible power options—ideal for garages, job sites, marinas, and remote locations where an outlet may not be available. Note: fuel canister and batteries are not included; confirm adapter and hose sizes before use.
