How to replace the fuel rail assembly on GMC Sierra 1500?

You must detach the air cleaner outlet duct before starting to replace the Fuel Rail assembly. Use ch-48027 to relieve fuel system pressure or follow the applicable procedure. Start by detaching the engine wiring harness bracket nut before disconnecting the external electrical connectors from the evap purge solenoid, generator and MAP Sensor, evap purge solenoid, generator, ignition coil main connector, electronic throttle control. Start by marking the Fuel Injector electrical connectors for reassembly but disconnecting them from their location. Remove the cpa retainers to disconnect other connectors. Detach the engine wiring harness clips alongside the negative Battery Cable from the right cylinder head. The technician disconnects the quick connect fitting of the chassis fuel feed pipe while also taking off the evap tube quick connect fittings at both the intake manifold and the evap canister purge solenoid. You should first remove the retainer locking the evap canister purge solenoid to the Fuel Rail before removing the Fuel Rail bolts and carefully moving the entire Fuel Rail assembly to protect its injector electrical connector terminals together with spray tips. After cleaning the Fuel Rail users must extract the Fuel Injector retainers and fuel injectors with disposal of original upper and lower o-ring seals (2 and 4). The installation begins with engine oil lubrication of new o-ring seals followed by placement on the injectors before inserting them into the Fuel Rail. Handle the Fuel Rail retainers first before arranging the Fuel Rail on the intake manifold and pushing it to achieve full seating. First install the Fuel Rail bolts while tightening them to 10 nm (89 lb in) then reconnect the evap tube and purge solenoid and the chassis fuel feed pipe by installing the quick connect fitting. Gather the engine wiring harness branches and reinstall the pcv hose before using the clips for connection. The engine wiring harness bracket nut requires installation at 5 nm to 44 lb in torque. At this time, connect the negative Battery Cable while ensuring all electrical connections are correctly in place. The process ends with turning on the ignition to verify for leaks before installing the air cleaner outlet duct.
