Buyer's checklist
What to check before buying a used fuel pump
- Match pump assembly module numbers, tank lock ring style, and quick-connect fuel line fitting diameters and counts (feed, return, and vapor lines).
- Check electrical connector pins for signs of heat scorching or melting, which indicates high current draw from an overheating motor.
- Inspect fuel level sender float arm and resistor wiper board for wear or corrosion that causes inaccurate gas gauge readings.
- Confirm whether the donor vehicle ran on standard gasoline, flex-fuel (E85), or diesel, as internal pump materials and flow rates vary accordingly.
