CLEAN AND INSPECT

CAUTION:
If it is necessary to remove rust or burrs from the male tube end of a quick-connect fining: use emery cloth in a radial motion with the tube end to prevent damage to O-ring sealing surfaces.


- Using a clean shop towel, wipe off male tube ends.

- Inspect all connectors for dirt and burrs. Clean or replace components / assemblies as required.

INSTALL OR CONNECT

WARNING: To Reduce the Risk of Fire and Personal Injury:

- Before installing a new filter, always apply a few drops of clean engine oil to the male tube end of the filter and to the fuel level meter assembly. This will ensure proper reconnection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper re-connection if not lubricated).

1. Apply a few drops of clean engine oil to the male tube end of the filter and of the fuel sender assembly.
2. Push connectors together to cause the retaining tabs / fingers to snap into place.
3. Once installed, pull on both ends of each connection to make sure they are secure.
4. Inspect for leaks.
A. Turn the ignition switch ON for 2 seconds.
B. Turn the ignition switch OFF for 10 seconds.
C. Turn the ignition switch ON.
D. Visually inspect the fuel system for fuel leaks.
5. Reposition the dust cover over the quick connect fitting.
