2005 Lincoln LS Fuel Rail Parts Questions & Experts Answers

• Q: What are the crucial safety precautions and steps to follow when servicing the fuel rail on 2005 Lincoln LS?

  A: The necessary safety precautions should be observed when servicing the fuel rail because it contains highly flammable mixtures. All work should begin after disconnecting the battery ground cable. The mechanic must eliminate the engine appearance cover together with its noise suppressor before work begins. The noise suppressor needs to return to its position on the intake manifold before cover replacement. Relieving the fuel system pressure becomes necessary after removing the air cleaner outlet pipe. You must detach the fuel temperature sensor electrical connector before removing the four engine appearance cover mounting bracket nuts and brackets and disconnecting both the fuel pressure sensor electrical connector and vacuum connector and the eight fuel injector electrical connectors. Separate the fuel supply tube retaining clip together with the spring lock coupling before taking out the four bolts securing the fuel injection supply manifold and fuel injectors. The removal of injectors warrants a disposal of 16 O-ring seals while replacing them with fuel-resistant seals because standard seals tend to cause leaks. Clean engine oil must be used for lubricating new O-ring seals before and after aligning fuel tube fittings by applying pressure until an audible click sound occurs which should be confirmed through a pull test for full engagement. Little torque of 6 Nm (53 lb-in) should apply when tightening engine appearance cover mounting bracket nuts and fuel injection supply manifold bolts reach 9 Nm (80 lb-in).
