  Q: How should one service the fuel injector and fuel rail safely and effectively on Lincoln MKZ?

  A: The servicing procedure demands users to stay away from smoking or open fire situations around fuel components because flammable mixtures exist during work. Relieving fuel system pressure should be your first step before you disconnect the battery ground cable. Start by taking off the upper intake manifold and continuing to disconnect two components: the fuel tube-to-Fuel Rail spring lock coupling along with the six fuel injector electrical connectors. To proceed remove first the four fuel rail bolts after which you can take out the fuel rail together with its injectors. You should remove the fuel injector clips then dispose of both the six fuel injector clips along with the twelve fuel injector O-ring seals. Use new special fuel-resistant O-ring seals which must be used separately between upper and lower positions while being lubricated with engine oil of high cleanliness. The fuel rail assembly needs installation with six fuel injectors along with their clips before attaching it back to the vehicle with its four bolts at 10 Nm (89 lb-in). Reconnect the battery ground cable and install the upper intake manifold after finishing the six fuel injector electrical connector and fuel tube-to-fuel rail spring lock coupling process.
