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.
