koulate Portable Fuel Transfer Pump 3.2 GPM — 12V/AA Battery Powered, Auto-Stop with 51" Hose & 4 Adapters

The Koulate Portable Fuel Transfer Pump is a lightweight, battery- or 12V-powered pump that safely moves gasoline, diesel, oil or water at up to 3.2 GPM and auto-stops when the receiving tank is full.

This compact pump is built for quick, on-the-spot refueling and fluid transfer where standard pumps aren't practical. Combining a fast-flow motor, universal adapters and safety cutoffs in a rugged, easy-to-grip package, it replaces slow siphoning and bulky shop pumps for roadside, farm, marine and emergency use.

How fast and reliable is the pump for everyday transfers?

The motor delivers a high flow rate that gets fuel moved quickly while maintaining a consistent stream during operation. Its three-adapter sealing system prevents drips and keeps pressure steady so transfers finish in a fraction of the time compared with manual methods.

• Flow capacity rated around 3.2 gallons per minute for rapid transfers.
• Three universal adapter sizes to fit most jerrycans and fuel necks.
• Designed for repeat use — suited for multiple vehicle and equipment refills.

What safety features prevent spills and accidents?

Safety is handled by both automatic and audible protections: the pump stops itself when the receiving tank reaches capacity and sounds an alarm if the hose becomes disconnected. These layered controls reduce overflows and warn the operator to take action immediately.

• Auto-shutoff senses backpressure and halts flow when the tank is full.
• Audible alarm alerts you to hose disconnection or interruption.
• Sealed adapter fittings minimize leakage during connection and removal.

Will it stand up to rough use and outdoor conditions?

The housing and hose are selected for durability and temperature tolerance so the unit works in harsh environments. Materials resist puncture, crushing and extreme temperatures, making it suitable for farm, marine and roadside tasks where gear often gets roughed up.

• Crush-resistant ABS housing to resist drops and impacts.
• Military-grade PVC hose rated for low and high temperatures.
• Proven performance after heavy-duty testing and field use.

How do I power it and what comes in the kit?

The pump runs from a standard 12V battery or AA batteries for flexibility when mains or vehicle power isn’t available. The kit includes multiple adapters and a long hose so you can connect to most containers without extra tools or fittings.

• Operates on 12V DC or AA batteries for off-grid use.
• Includes a 51-inch hose for easy reach into tanks and recessed openings.
• Four universal adapters cover common thread sizes and spouts.

Who is this for: Professionals and owners who need a compact, dependable solution for moving fuels and liquids — including mechanics, farmers, boaters, landscapers and anyone assembling a vehicle or emergency kit. If you want a portable transfer pump that balances speed, safety and durability without hauling a heavy shop pump, this unit is designed for that purpose.
