^ Inspect both ends of the fitting for dirt and burrs. Clean or replace components as required.

Installation Procedure

Caution: In order to Reduce the Risk of Fire and Personal Injury: Before connecting the fuel pipe quick-connect fitting, always apply a few drops of clean engine oil to the male fuel pipe end.

2. Push both sides of the quick-connect fitting together in order to cause the retaining tabs to snap into place.
