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?
