Quick-Connect Fittings:

QUICK-CONNECT FITTINGS
Quick-connect type fittings provide a simplified means of installing and connecting fuel system components. There are three types of quick-connect fittings used at different locations in the fuel system. Each type consists of a unique female socket and a compatible male connector. O-rings, located inside the female socket, provide the fuel seal. Integral locking tabs or fingers hold the fittings together.

FUEL PIPE O-ringS
Fuel feed threaded connections at the fuel filter are sealed with replaceable O-ring seals. These O-rings seals are made of special material, and should only be serviced with the correct service part.
