TRUPOW 12V Fuel Transfer Pump — 3.7 GPM Self-Priming, Reversible Flow, Cast-Iron

TRUPOW's 12V self-priming transfer pump quickly moves gasoline, diesel, kerosene and similar fuels at up to 3.7 gallons per minute with reversible flow for easy filling or draining.

This compact, vehicle-ready pump pairs a copper-wound 1/10 HP motor with a cast-iron sealed chamber and explosion-proof components to deliver safe, on-site fuel transfers. Built for portability, the unit runs from a 12V DC source and offers reversible pumping, thermal protection, and a built-in bypass to reduce backflow. It’s engineered for routine refueling, tank draining, and fluid handling where thin-viscosity petroleum products are used.

How fast and how far can this pump move fuel?

The pump delivers up to 3.7 gallons per minute and features a maximum suction lift of about 4.9 feet and a maximum discharge lift near 19 feet. That combination supports quick transfers from portable drums or service tanks into vehicles and equipment.

• Flow rate: up to 3.7 GPM for efficient transfers
• Suction capability: max 4.9 ft for drawing from low sources
• Discharge lift: up to 19 ft for pumping uphill or into elevated tanks
• Motor type: 1/10 HP with solid copper windings for steady torque

Is this pump safe and durable for fuel handling?

Safety is addressed through explosion-proof components that reduce spark risk and a sealed cast-iron pump chamber that withstands field use. Thermal protection stops the motor if it overheats, and an internal bypass minimizes backflow during operation.

• Explosion-proof parts to lower ignition risk
• Cast-iron sealed pump chamber for rugged durability
• Automatic thermal cut-off to prevent motor damage
• Built-in bypass prevents unwanted reverse flow

Can I reverse flow without disconnecting hoses?

Yes — the integrated switch supports reversible pumping so you can change the flow direction with a single control press. That makes it simple to switch between filling and draining without moving fittings or hoses.

• One-button reversible operation for convenient switching
• Works with thin-viscosity petroleum fuels including gasoline, diesel and kerosene
• Supports common fuel blends (up to E15 gasoline, B20 diesel)
• 1/2" NPT inlet/discharge for high-capacity connections

What accessories and maintenance guidance are included?

The pump ships with a set of fittings, clamps and a sealing gasket to get you running quickly, and its lightweight design makes it easy to store and transport. Recommended operating practice is to run no more than 30 minutes continuously to prolong motor life and follow routine inspection for leaks and clamp tightness.

• Includes one pump body, sealing gasket, four fittings and four hose clamps
• Lightweight for easy portability and storage
• 12V DC operation for vehicle, boat, or portable battery use
• Recommended 30-minute running-cycle to avoid overheating

Who is this for: The TRUPOW 12V self-priming transfer pump is intended for DIY mechanics, fleet operators, boaters, caravan and RV owners, farmers, and small equipment users who need a portable, reversible pump for handling gasoline, diesel, kerosene and similar thin petroleum fluids. It suits anyone needing reliable, on-site transfers from drums, tanks or vehicles while prioritizing durability and basic safety features.
