Fuel Injector: Service and Repair

WARNING: FIRE HAZARD! Disconnect battery ground strap when working on the fuel system. Do not smoke or create any sparks where odor of fuel vapor is present.

Removing/replacing the injectors on this engine is a simple matter of un-bolting the retaining brackets from the intake manifold and pulling the injectors from their sockets. If injectors must be removed from fuel lines, slowly and carefully loosen the fuel line connection at each injector to relieve the residual pressure in the lines.

NOTE: If the injectors are removed for any reason, you should also remove the air shroud inserts and replace all the O-ring seals. Once removed, O-rings must be replaced. Lubricate new O-rings with gasoline before installing. If there are two colors of O-rings (black and red), install the black O-ring at the bottom of the insert.

CAUTION: The inserts are plastic and are very easily broken. Use a penetrating oil to help loosen them and work them gradually from their sockets until they are free.
