2008 Lincoln Navigator Fuel Rail Parts Questions & Experts Answers

• Q: How should one safely service the fuel rail and what steps are involved in the process on 2008 Lincoln Navigator?

  A: It is crucial to protect safety during fuel rail service because the presence of flammable mixtures requires users to stay away from fuel components when using lighted tobacco or open flames or when smoking. Releasing fuel system pressure first becomes essential before disconnection of any fuel tubes or components because high pressure conditions persist even while the engine is turned off. The process of handling fuel injection equipment should combine cleanliness protocols while using blanking plugs to seal open orifices and tubes to stop engine damage from occurring. Professionals should start by disconnecting the battery ground cable followed by disconnection of the fuel supply tube spring lock coupling. You should first remove the air cleaner outlet pipe and then disconnect the quick connect couplings to detach the crankcase vent tube. You should detach the generator wiring harness retainer from the air cleaner outlet pipe-to-throttle body adapter before removing the four bolts which secure this adapter. Before restoring the adapter apply engine coolant to the seal and tighten each bolt to 10 Nm (89 lb-in). Proceed with the removal of the PCV tube by unfastening the quick connect couplings after you disconnect the electronic throttle control and throttle position sensor and heated PCV intake fitting and the eight fuel injector electrical connectors. Reinstall the fuel rails using the same torque pattern of 10 Nm (89 lb-in). You should extract the fuel rail together with fuel injectors before removing their eight locking clips. Special engine oil lubrication of new fuel-resistant O-ring seals is required before use. Replace all old seals during the installation process. Execution of the reverse removal process completes the installation procedure.
