TERA PUMP 5th Gen TRFA01 Fuel Transfer Pump — Battery-Powered, Auto-Stop Overfill Protection, 2.7 GPM

The TERA PUMP 5th Gen TRFA01 is a battery-powered fuel transfer pump that moves gasoline, diesel, kerosene or non-potable water quickly and stops automatically to prevent spills.

Designed for homeowners, small fleet owners and outdoor enthusiasts, this upgraded transfer pump combines faster flow with spill protection and a universal adapter for most 3–5 gallon North American plastic gas cans. The latest generation brings a tougher vinyl discharge hose, improved impeller cover, an ergonomic nozzle and thread compatibility to reduce fumbling at the fuel can. It runs on AA batteries and is intended for short-term liquid transfers where portability and ease matter most.

How quickly can this pump move fuel?

Expect significantly faster transfers than a manual siphon. The TRFA01 delivers up to 2.7 gallons per minute, letting you move a 5-gallon container in roughly two minutes under ideal conditions. Battery life and liquid viscosity affect total throughput.

• Top flow rate: up to 2.7 GPM
• Typical output: about 250 gallons per set of 4 AA batteries
• Emergency option: operate on 2 AA batteries in center slots
• Intake hose length: flexible 18–21 inches to reach jug bottoms

Will it prevent overfill and spills?

Yes — the pump includes an automatic stop feature built into the nozzle that senses backflow and halts pumping to avoid overflow without user intervention. This helps reduce wasted fuel and messy cleanups when transferring into smaller containers.

• Auto stop sensor located at nozzle tip
• Automatic shutoff when receiving container is full
• Reduces fuel loss and cleanup time
• No need to manually watch the transfer continuously

What liquids and can sizes are compatible?

The TRFA01 works with gasoline (including E15), diesel, kerosene and non-potable water; prolonged exposure to high‑ethanol blends like E85 can degrade certain seals. The pump ships with a redesigned threaded adapter that fits many common North American plastic gas cans, simplifying setup.

• Compatible liquids: gasoline, E15, diesel, kerosene, non-potable water
• Not recommended for continuous E85 contact due to seal wear
• Universal adapter fits most 3–5 gal Briggs & Stratton, No-Spill, Midwest cans
• Not compatible with FMD fittings unless removed first

How is this version improved over previous models?

The 5th generation focuses on durability and user comfort: a longer vinyl discharge hose resists nicks, a metal impeller cover shields internal parts from debris, and the nozzle handle is reshaped for easier gripping. Small refinements like thread sizing on the adapter reduce setup time.

• 39.4-inch vinyl discharge hose for abrasion protection
• Upgraded metal impeller cover to block debris
• Ergonomic nozzle handle reduces hand strain
• Refined universal adapter for faster can attachment

Who is this for? The TERA PUMP TRFA01 5th Gen is made for anyone who needs a portable, fast and cleaner way to move fuel and similar liquids: homeowners topping off lawn equipment, boaters filling portable tanks, mechanics working with multiple cans, or first responders needing a compact transfer solution. It’s best when portability, quick transfer speed and spill reduction matter more than continuous industrial pumping; batteries (AA) keep it cordless and ready wherever a short, reliable transfer is needed.
