BYERNAUTO cordless automatic fuel transfer pump 3.2 GPM — battery-powered, auto-stop for spill reduction

BYERNAUTO's cordless automatic fuel transfer pump is a battery-powered 3.2 GPM gas-can pump with auto-stop sensor for fast, spill-reducing refueling from cans to tanks.

Designed for RV owners, truckers, boaters and backyard mechanics, this compact BYERNAUTO transfer pump moves gasoline, diesel, kerosene, water and light oils without heavy lifting or extension cords. The unit runs on AA batteries, includes four adapters to fit most filler necks, and uses an auto-stop sensor that halts flow when a receiving tank is full — helping reduce mess and overfills. Weather-resistant hose materials and an overload-protected, explosion-rated motor let you use it outdoors or in garages with added safety and quiet operation.

How quickly will this pump move fuel and what applications suit a 3.2 GPM rate?

The pump delivers up to 3.2 gallons per minute, making it practical for filling everything from portable gas cans to mid-size RV or boat fuel tanks. That flow rate balances speed with control for smaller refueling jobs without the need for heavy manual pouring.

• Flow rate: up to 3.2 GPM for fast transfers
• Best for: gas cans, small to medium tanks, generators, ATV/UTV refills
• Compatible liquids: gasoline, diesel, kerosene, water, light oils

Does the BYERNAUTO pump prevent spills and how does the auto-stop work?

The built-in sensor detects liquid level in the receiving tank and automatically shuts off the pump when the tank reaches capacity, reducing spills and wasted fuel. For reliable operation keep the sensor submerged and clean; avoid running the pump dry to prevent damage.

• Auto-stop sensor stops flow when tank is full
• LED indicator shows pump on/off status for easy visibility
• Recommended maintenance: keep sensor clean and remove batteries when idle

What power source does it use and can it run in emergencies?

The BYERNAUTO pump is cordless and powered by four AA batteries (not included) for everyday portability. In a pinch the unit can operate on two AA batteries in emergency mode, giving you flexibility when mains power isn’t available.

• Primary power: 4 AA batteries for normal operation
• Emergency mode: runs on 2 AA batteries if required
• Portable: no cords, light enough to carry for roadside use

Which fuel cans and fittings will this pump fit?

The pump comes with one fixed 1.3-inch adapter and three removable adapters sized 1.9, 2.3 and 2.5 inches, covering most standard fuel can openings. These included fittings, together with a flexible, corrosion-resistant hose, make the pump adaptable to a wide range of containers and funnels.

• Included adapters: 1.3", 1.9", 2.3", 2.5" for broad compatibility
• Hose: weather- and corrosion-resistant for outdoor use
• Works with common can types and tank inlets for easy setup

Who this is for: The BYERNAUTO automatic fuel transfer pump is aimed at anyone who needs a fast, portable way to move small-to-medium amounts of fuel without spills — RV owners topping off tanks, homeowners filling generators, boaters refueling small craft, landscapers and mechanics working with portable cans. If you want a battery-powered, easy-to-use pump with auto-stop protection, multiple adapter sizes, and quiet, safe operation, this pump is designed to simplify refueling tasks while minimizing mess.
