2005 Chevrolet Classic Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the fuel rail assembly on 2005 Chevrolet Classic?

  A: The first step for Fuel Rail assembly replacement demands fuel system pressure reduction. You need to remove the air cleaner outlet resonator before disconnecting the vacuum pipe from the Fuel Pressure Regulator while also removing the engine fuel supply and return pipes. Remove the Fuel Rail attaching studs after disconnecting the Fuel Injector harness connectors from their sockets. Pull the Fuel Rail to the top and backward direction until the injectors separate from cylinder head ports. Then tilt the rail down to continue installation. Follow proper caution when working to prevent damage to the electrical connector terminals and spray tips of the fuel injectors. Next, remove the fuel injectors. The installation procedure starts with installing fuel injectors which must receive new lower o-rings and the injector tip o-rings require lubrication before placing them into the Intake Manifold. The installation of fuel injectors begins with a downward position followed by lowering them into cylinder head ports after rotating the Fuel Rail forward and pushing them carefully into place. The Fuel Rail attaching studs need installation with torque set to 10 n.m (89 lb in). Attach the Fuel Injector harness connectors until they lock securely and install the fuel supply and return pipes followed by vacuum pipe connection to the Fuel Pressure Regulator then install the air cleaner outlet resonator. For the final step inspect the vehicle for fuel leaks by switching on the ignition while keeping the engine off during two seconds and waiting ten seconds with ignition off before repeating the ignition test for leaks.
