ENGINEMAN 3.2 GPM Battery-Powered Fuel Transfer Pump — 51" Hose, USB-C & Hand Shut-Off Nozzle

The ENGINEMAN 3.2 GPM battery-powered fuel transfer pump is a portable, spill-resistant solution for fast, controlled transfer of gasoline, diesel, kerosene and light oils.

This compact pump combines battery or USB-C power with a manual shut-off nozzle and a long, flexible discharge hose so you can refill generators, lawn equipment, boats, ATVs and vehicles quickly and with less mess. The kit includes four common adapters to fit a wide range of container mouths and a durable corrugated 51-inch discharge hose to reach recessed tanks. It’s designed for one-button operation and comes with a storage bag and a one-year warranty for confidence during use.

How fast and efficient is the pump for everyday refilling?

The ENGINEMAN pump delivers a high flow rate of up to 3.2 gallons per minute, moving fuel much faster than hand siphons or small manual pumps. That speed reduces downtime when topping off a generator or filling multiple machines.

• 3.2 GPM maximum flow for rapid transfer
• One-touch start for quick operation
• Saves time versus manual pouring and prevents repeated trips

What power options are available if I’m off-grid?

Use four AA batteries to run the pump away from shore power, or connect a USB-C cable for continuous operation from a power bank or vehicle adapter. In low-battery situations you can still operate with two batteries in an emergency, giving extra flexibility when access to electricity is limited.

• Primary: 4 AA batteries (compatible with 2 in emergencies)
• Alternative: USB-C wired power for power banks and car chargers
• Lightweight design keeps spare batteries and a cable practical to carry

Will it fit my fuel cans and vehicle tanks?

The pump ships with four universal adapters sized to match most North American fuel can openings, and the corrugated 51-inch discharge hose helps you reach recessed filler necks. Always confirm your can’s mouth diameter before use to ensure a secure connection and minimize leaks.

• Included adapter sizes: 2.0", 2.1", 2.75", 3.75"
• 22" intake hose plus 51" discharge for extended reach
• Works with lawn mowers, generators, tractors, ATVs, boats, RVs

How does the nozzle and design reduce spills and make storage easier?

The manually operated shut-off nozzle gives you immediate control over fuel flow, helping prevent overfills and drips at the tank inlet. The pump’s anti-drip layout, compact footprint and included storage pouch keep the unit tidy in a garage or vehicle without risking messy leaks.

• Hand shut-off nozzle for instant flow stop
• Leak-resistant fittings and anti-drip outlet design
• Compact form factor with storage bag for clean transport

Who is this for? The ENGINEMAN 3.2GPM Battery Powered USB Charging Fuel Transfer Pump is ideal for homeowners, landscapers, boaters, RV owners, and anyone who needs a portable, faster, and cleaner way to move gasoline, diesel, kerosene or light oils. If you need a quick refill for generators, lawn equipment or recreational vehicles without lifting heavy cans or risking spills, this kit provides adapters, reach and power options to make transfers straightforward and dependable.
