AIDERAR 3.8 GPM Fuel Transfer Pump Battery Operated, Auto-Stop Nozzle & 71" Hose

The AIDERAR 3.8 GPM Fuel Transfer Pump is a battery-powered, portable liquid pump with an auto-stop nozzle and multiple adapters for safe, spill-reducing transfers.

This lightweight pump is designed to move gasoline, diesel, kerosene and many liquids quickly without lifting or tilting heavy containers. Running on four AA batteries, it pushes up to 3.8 gallons per minute through a long discharge hose and stops automatically when the receiving tank is full. With a selection of adapters and a built-in 2.5" fitting, it fits most common U.S. gas cans and utility jugs for everyday automotive, marine and yard tasks.

How fast and what liquids can I transfer with this pump?

The AIDERAR unit delivers up to 3.8 GPM, which makes short work of refueling small tanks and draining portable containers. It handles gasoline, diesel, kerosene, antifreeze, windshield washer fluid, light oils and mild detergents. Note that higher-ethanol blends (E15–E50) can accelerate seal wear, and you should avoid leaving the pump submerged for long periods.

• Flow rate: up to 3.8 gallons per minute for quick transfers.
• Compatible fluids: gas, diesel, kerosene, antifreeze, light oils, washer fluid, mild detergents.
• Ethanol warning: E15–E50 usable but may shorten seal life.
• Do not submerge pump long-term to protect motor and seals.

How does the auto-stop nozzle make refueling easier and safer?

The pistol-style nozzle automatically stops flow once the receiving tank reaches capacity, reducing overflows and messy spills. The ergonomic grip improves one-handed control and the automatic shutoff helps when refueling cars, lawn equipment, generators or marine tanks. This feature is especially helpful during repetitive refills or when visibility into the tank is limited.

• Automatic shutoff prevents overfilling and fuel waste.
• Ergonomic nozzle for controlled, comfortable handling.
• Reduces fuel drips when disconnecting the hose after fill-up.

Will it fit my gas can and reach deep tanks?

AIDERAR includes a 71-inch discharge hose and a 31.5-inch suction tube to access deep or awkward containers. The kit contains four external adapters (2", 2.1", 2.75", 3.75") plus a built-in 2.5" adapter to accommodate most popular U.S. gas cans. Always verify your container’s neck size; it is not compatible with some specialty jugs like Tuff Jug and Gas Caddy.

• 71" discharge hose for versatile reach to tanks and equipment.
• 31.5" suction tube to draw from deep or tall containers.
• Adapters: built-in 2.5" plus 2", 2.1", 2.75", 3.75" for wide compatibility.
• Check compatibility: not suitable for certain brands (e.g., Tuff Jug).

How do I power and maintain the pump for reliable use?

The pump runs on four AA batteries (not included), making it fully portable without cords or external power. Swap batteries quickly in the field to maintain performance; alkaline or rechargeable AA cells work. For longevity, avoid leaving the pump immersed, drain hoses after use and remove any container filters before operation to prevent reduced flow.

• Powers with 4 AA batteries for cordless convenience.
• Use fresh alkaline or quality rechargeable cells for best output.
• Remove container filters before pumping to prevent blockages.
• Drain and store dry when not in use to preserve motor and seals.
