6.7L Cummins Injectors and Fuel Lines – Fuel Filter Head – Clean and Inspect for Reuse

For front gear train engines, verify the screened quick- connect fitting on the outlet side of the fuel filter housing
is free of debris.
If debris is found, rinse the screen with an evaporative cleaner.
Replace the fitting if the debris can not be removed.

Inspect the fuel filter head for cracks, passage blockage, and material or debris on the sealing surfaces.
