Fuel Rail Assembly Replacement - Bank 2

FUEL RAIL ASSEMBLY REPLACEMENT - BANK 2

REMOVAL PROCEDURE




1. Disconnect the negative battery cables.
2. Remove the air cleaner outlet duct.
3. Remove the fuel injection control module (FICM).
4. Remove the fuel filter.
5. Remove the exhaust gas recirculation (EGR) cooler tube.
6. Remove the positive crankcase ventilation (PCV) hose/pipe.
7. Disconnect the fuel rail balance pipe from the fuel rails.
8. Remove the fuel rail balance pipe bolts.
9. Remove the fuel rail balance pipe.




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.

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.

12. Remove the fuel injector pipes.




13. Remove the fuel rail bolts.
14. Remove the fuel rail.

INSTALLATION PROCEDURE

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.




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

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

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.




3. Install the fuel injector pipes.

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




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

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

6. Install the fuel rail balance pipe bolts.

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

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