2006 Lincoln Town Car Fuel Rail Parts Q&A

• Q: How should one service the fuel rail while ensuring safety and preventing leaks on 2006 Lincoln Town Car?

  A: The presence of flammable mixtures during fuel rail servicing requires workers to keep away from both smoking and open flame devices near fuel-related parts. The system requires pressure relief before any fuel component disconnection to stop unwanted spray of fuel. The first step requires fixing the vehicle on a hoist into the neutral position while uninstalling the battery ground cable. First detach the spring lock coupling on the fuel rail before taking out the throttle body (TB) and exhaust gas recirculation (EGR) system module to exhaust manifold tube. All components such as the brake booster vacuum hose and evaporative emission (EVAP) canister purge valve hose and positive crankcase ventilation (PCV) tube and intake manifold vacuum hose should be detached from the throttle body spacer before setting them aside for further work. Begin by detaching the crash bracket wire harness retainer and remove any crash bracket bolts which might apply. The left-hand front fuel rail stud bolt receiver should be unclipped while all eight fuel injector electrical connectors get detached together with the right-hand rear fuel rail stud bolt ground connection. The disconnect procedure includes separating the fuel rail pressure and temperature sensor vacuum connections from the electrical connectors while also removing the vacuum and electrical attachments of the EGR system module. Start the removal sequence by removing first the shield bolts and shield and afterward the fuel rail stud bolts which total four in number. The technicians uninstall the fuel rail assembly together with its fuel injectors. The installation procedure demands new fuel-resistant O-ring seals which should replace all previous O-rings due to leak prevention needs. Reposition your fuel injectors from the fuel rail and apply engine oil to the O-ring seal components before following the opposite order for installation. Use tight torque values of 25 Nm (18 lb-ft) for crash bracket bolts and 12 Nm (9 lb-ft) for intake manifold shield bolts as well as 10 Nm (89 lb-in) for fuel rail stud bolts.
