The TOPWAY pump is rated up to 3.7 gallons per minute under normal conditions, allowing fast transfer of gasoline, diesel and other light oils. It features a self-priming design and can achieve a maximum suction lift of about 4.9 feet, suitable for typical tank-to-tank or drum transfers.

What safety and durability features are included?

How do I operate and install the pump for different tasks?

Installation is straightforward: attach the correct hose adaptor and clamps from the included kit, connect the 12V power source, and use the dual-direction switch to select forward or reverse flow. The portable handle and compact footprint make it easy to transport and store, and the pump is suited for both filling and emptying operations.

What maintenance and usage tips help extend life and performance?

Keep the pump clean of debris and avoid running it dry to protect the internal seals and motor. Use compatible hoses and secure clamps to prevent leaks, and follow routine checks for loose connections, wear or damage. The handle and mounting screws are shipped separately in a small bag to reduce package size—install with a screwdriver before first use.

• Avoid dry running and flush with an appropriate solvent after use if needed
• Inspect hoses, clamps and electrical connections regularly
• Install handle and fasteners supplied in the small bag prior to transport
