Fuel Injector Feed Pipes Replacement - Right

FUEL INJECTOR FEED PIPES REPLACEMENT - RIGHT

REMOVAL PROCEDURE




1. Remove the engine cover.
2. Remove the exhaust gas recirculation cooler, if necessary.




3. Prior to removing the fuel injector pipes, use compressed air to blow any debris from between the injector line and fittings. Wipe the fittings clean of debris.
4. Spray lithium grease, GM P/N 12346293 or equivalent, between the fuel injector line and fittings to assist in containing any debris during removal.
5. Remove the fuel injector pipes.

NOTE: DO NOT use compressed air to clean debris from the fuel injector inlet after the fuel line is removed. Using compressed air can allow debris to enter the fuel injector inlet and damage the fuel injector.

INSTALLATION PROCEDURE

NOTE: Ensure proper torquing of the fuel injector line. An under-torqued fuel injector line will not seal properly and an over-torqued fuel injector line may damage the fuel injector fitting. An improperly sealed or damaged fuel injector line or fuel injector fitting will cause a fuel leak.




1. Install the fuel injector pipes.

NOTE: Refer to Fastener Notice.

Tighten the fittings to 41 N.m (30 lb ft).

2. After installing the fuel injector pipes, clean the injector pipes and apply sealant GM P/N 97720043, at the fittings to prevent moisture and debris from collecting between the line and fitting.
3. Install the EGR cooler, if removed.




4. Install a NEW quick connect fitting clip to the charged air cooler duct.
5. Install the charged air cooler outlet duct to the intake.
6. Prime the fuel system. Refer to Fuel System Priming.
7. Start the engine. If the engine stalls, repeat the above step.
8. Once the engine starts, inspect for fuel leaks.
9. Install the engine cover.
