Troubleshooting & FAQ

How do I confirm this part fits my specific engine?

The best way is to compare your original part's number to the ones listed in our Part Number Matrix. Additionally, check your engine's model, HP, year, and serial number against the compatibility table. If your part or model is not listed, this part may not fit.

What are common signs of a failing fuel pump?

Symptoms of a bad fuel pump include the engine bogging down at high speeds, difficulty starting, sputtering, or a complete failure to start. These issues occur when the pump can no longer supply the engine with a consistent, adequate flow of fuel.

Is a mounting gasket included with this fuel pump?

This kit includes the fuel pump assembly only. Mounting gaskets or other hardware are not typically included and may need to be purchased separately depending on your application's requirements.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
