Fuel Injection Fuel Feed Pipe Replacement - Left Side
Removal Procedure
1. Remove the front exhaust gas recirculation cooler. Refer to Exhaust Gas Recirculation Valve Cooler Replacement (LGH) Exhaust Gas Recirculation Valve Cooler ReplacementExhaust Gas Recirculation Valve Cooler Replacement (LML-Rear) Exhaust Gas Recirculation Valve Cooler Replacement (Rear)Exhaust Gas Recirculation Valve Cooler Replacement (LML-Front) Exhaust Gas Recirculation Valve Cooler Replacement (Front).
2. Reposition the charge air cooler pipe from the turbo.
3. Remove the fuel rail pressure sensor bracket shield.
4. 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.
5. Spray lithium grease, GM P/N 12346293 or equivalent, between the fuel injector line and fittings to assist in containing any debris during removal.
Caution: 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.
6. Remove the fuel pipe bracket fasteners (1) and pipes (2).
Installation Procedure
Caution: 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.
Caution: Refer to Fastener Caution Fastener Caution.
1. Install the fuel injector pipes (2). Tighten the fittings to 30 Nm (22 lb ft).
2. Install the fuel pipe bracket fasteners (1) and tighten to 10 Nm (89 lb in).
3. 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.
4. Install the fuel rail pressure sensor bracket shield.
5. Reposition the charge air cooler pipe to the turbo.
6. Install the front exhaust gas recirculation cooler.

7. Start the engine.
If the engine stalls, repeat the above step.
8. Inspect the fuel system for fuel leaks.
