Troubleshooting & FAQ

How can I confirm this fuel pump is correct for my engine?

The most reliable method is to match your engine's serial number to the ranges listed in our Engine & Model Compatibility table. If your serial number falls within a specified range, this part is compatible.

What are the signs of a failing fuel pump?

Common symptoms include the engine sputtering at high speeds, loss of power, surging, difficulty starting, or bogging down under acceleration. A fuel pressure test can also diagnose a weak pump.

Does this part fit DFI and DTS models?

Yes, this pump is compatible with specific DFI and DTS models as noted in the compatibility chart, where it replaces OEM part number 14360T74.

Is any special maintenance required for this fuel pump?

Mechanical fuel pumps like this are generally maintenance-free. However, using clean, high-quality fuel and replacing fuel filters at recommended intervals will extend its service life.
