Fuel Line Coupler: Service and Repair
Plastic Retainer Type
Fig. 15 Plastic Retainer Ring Type Fitting
This type of fitting can be identified by the use of a full-round plastic retainer ring usually black in color.
CAUTION: The interior components (0-rings, spacers, retainers) of this type of quick-connect fitting are not serviced separately. Do not attempt
to repair damaged fittings or fuel lines/tubes. If repair is necessary, replace the complete fuel tube assembly.
WARNING: The fuel system is under a constant pressure (even with the engine off). Before servicing any fuel system hoses, fittings or
lines, the fuel system pressure must be released. Refer to the fuel system pressure release procedure.
DISCONNECTION/CONNECTION

4. To release the fuel system component from the quick-connect fitting, firmly push the fitting towards the component being serviced while firmly
pushing the plastic retainer ring into the fitting. With the plastic ring depressed, pull the fitting from the component. The plastic retainer ring must
be pressed squarely into the fitting body. If this retainer is cocked during removal, it may be difficult to disconnect fitting. Use an open-end wrench
on the shoulder of the plastic retainer ring to aid in disconnection.
