Removal Procedure
1. Relieve the fuel system pressure before servicing any fuel system connection. Refer to the Fuel Pressure Relief.
2. Remove the retainer from the quick-connect fitting.
Caution: Wear safety glasses when using compressed air, as flying dirt particles may cause eye injury.
3. Blow dirt out of the fitting using compressed air.
4. Choose the correct tool from the J37088-A for the size of the fitting. Insert the tool into the female connector, then push inward in order to release
the locking tabs.
5. Pull the connection apart.
Notice: If necessary, remove rust or burrs from the fuel pipes with an emery cloth. Use a radial motion with the fuel pipe end in order to prevent
damage to the O-ring sealing surface. Use a clean shop towel in order to wipe off the male tube ends. Inspect all the connections for dirt and burrs.
Clean or replace the components and assemblies as required.
