Limitation: confirmation of fuel compatibility with the premium filter is advised for specialized fuels or biodiesel blends.
Buying Guide
What to consider when choosing an auxiliary fuel tank pump kit:
- Flow rate needs: If you transfer large volumes quickly, prioritize higher GPM (gallons per minute) pumps like 20 GPM or more. For small operations, lower GPM with adequate headroom is fine.
- Fuel type compatibility: Ensure the pump is suitable for gasoline, diesel, kerosene, ethanol blends, or biodiesel as required.
- Electrical requirements: Check voltage (12V) and current draw. Ensure your vehicle or power source can support the draw without blowing fuses.
- Durability and environment: Cast-iron or heavy-duty housings offer longer life in rugged settings. Look for IP ratings for water and dust resistance if used outdoors.
- Installation complexity: Some kits include hoses, clamps, and mounting hardware; others require additional fittings. Consider whether a DIY install fits your schedule.
- Filtration and protection: Premium filters protect engines from particulates. Verify the presence of thermal protection or overheat safeguards.
