Fig. 5 Plastic Quick-Connect Fittings:

FUEL LINES AND QUICK CONNECT FITTINGS
Fuel Lines
Fuel line clamps are not used on any fuel system component. If there is a fitting or line that needs repair it must be replaced. DO NOT use rubber hose and clamps to repair a fuel line.

Inspect all lines and quick connect fittings for leaks. Replace lines that rub against other vehicle components or show sign of wear. Ensure all lines are secured in their proper holders.

Quick - Connect Fittings
Fuel tubes connect fuel system components with plastic quick-connect fuel fittings. The fitting contains non-serviceable 0-ring seals Fig. 5.

CAUTION: Quick-connect fittings are not serviced separately. Do not attempt to repair damaged quick-connect fittings or fuel tubes. Replace the complete fuel tube/quick-connect fitting assembly.

The quick-connect fitting consists of the 0-rings, retainer and casing Fig. 5. When the fuel tube enters the fitting, the retainer locks the shoulder of the nipple in place and the 0-rings seal the tube.
