8. Remove the fuel rail balance pipe.




9. Remove the wiring harness retainer from the bracket.




10. 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.
11. Spray lithium grease, GM P/N 12346293 or equivalent, between the fuel injector line and fittings to assist in containing any debris during removal.
12. Remove the fuel injector pipes.

INSTALLATION PROCEDURE




1. Install the fuel rail.
2. Install the fuel rail bolts.

NOTE: Refer to Fastener Notice.

Tighten the bolts to 25 N.m (18 lb ft).




3. Install the fuel injector pipes.

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.

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

4. 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.




5. Install the fuel rail balance pipe.
6. Connect the fuel rail balance pipe to the fuel rails.

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

7. Install the fuel rail balance pipe bolts.

Tighten the bolts 25 N.m (18 lb ft).

8. Install the PCV hose/pipe.
9. Install the EGR cooler tube.
10. Connect the negative battery cables.
11. Prime the fuel system. Refer to Fuel System Priming.
12. Start the engine. If the engine stalls, repeat the above step.
13. Once the engine starts, inspect for fuel leaks.
14. Install the engine cover.
