2002 Buick LeSabre Fuel Rail Parts Questions & Experts Answers

• Q: How to replace the fuel rail assembly (VIN K) on 2002 Buick LeSabre?

  A: You should start Fuel Rail assembly (VIN K) replacement operations by applying the j 43013 Fuel Injector remover to release fuel pressure from the system while cleaning up the area by sealing all fittings and holes to stop fuel from reaching the components. First clean all components of the Fuel Rail assembly and next disconnect both the fuel feed hose and the return hose from the Fuel Rail tubes and the vacuum line from the pressure regulator. To access the Fuel Injector connectors you should first remove ignition coil wires before lifting the lock release while depressing the lock tab to remove the connectors from the fuel injectors. Use the j 43013 to lift the injectors while you handle their removal of Fuel Rail hold-down bolts. Apply equal strength when extracting the Fuel Rail assembly. The installation process requires new o-rings on all serviced parts while the Fuel Injector o-rings need light motor oil application before seating the Fuel Rail assembly onto the Intake Manifold using hand force. Affix the Fuel Rail hold-down bolts while torquing them to 10 n.m (89 lb in). The first step includes hooking up Fuel Injector electrical connectors after pushing down the lock release lever until it latches in place while you also connect fuel feed and return pipes to the Fuel Rail tubes. Install the vacuum line back to the Fuel Pressure Regulator after which install ignition coil wires and tighten the fuel fill cap and finally attach the negative Battery Cable. Perform a leak inspection procedure by turning the ignition for two seconds followed by ten seconds off then on again and finally inspect for fuel leaks before putting the fuel injection sight shield in place.
