Quick-Connect Fittings

Print

Some early model vehicles do not have quick-connect fuel line fittings. On these vehicles, just make sure to use a back-up wrench on the fuel lines when disconnecting them.


NOTE
If your vehicle is equipped with metal quick-connect fittings, a special tool (J 37088A) or equivalent will be required to service the fittings.
