2001 Buick LeSabre Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the fuel rail assembly on 2001 Buick LeSabre?

  A: A replacement of the Fuel Rail assembly begins with releasing fuel pressure from the system before cleaning all Fuel Rail components and connections. You must detach the vacuum line from the Fuel Pressure Regulator while pulling out the fuel feed pipes and return pipes from the Fuel Rail tubes. After pulling up the lock release on the Fuel Injector connectors the lock tab can be depressed to lift the connectors away from the fuel injectors. Raise each injector with the Fuel Injector removal tool (J 43013) while being cautious about the procedure. Use equal pressure when extracting the Fuel Rail from both sides. Installation requires proper positioning of the Fuel Injector o-rings where the black o-ring stays toward the top and the brown o-ring faces downward. Install the Fuel Rail assembly on the Intake Manifold then seat all fuel injectors manually after applying a little motor oil to their o-rings. Fasten the Fuel Rail hold-down bolts while torquing them to 10 n.m (89 lb in). Lock the connectors by pushing down on the release lever. After that install the fuel feed and return pipes onto the tubes of the Fuel Rail. Submit the vacuum line to the Fuel Pressure Regulator after reconnecting it followed by the ignition coil wire installation and fuel fill cap tightening and negative Battery Cable connection. A leak inspection should be conducted by turning the ignition on for two seconds followed by ten seconds of off time and then two more seconds of ignition until any fuel leaks are located before putting in the fuel injection sight shield.
