2008 Ford Escape Fuel Rail Parts Q&A

• Q: How should one service the fuel rail while ensuring safety and proper installation on 2008 Ford Escape?

  A: You should maintain safety when working with the fuel rail since open flames and smoking need to be entirely avoided because the rail contains explosive fuel mixtures. The first step should focus on removing system pressure since the fuel pressure stays high from engine shut-off. To begin work on the fuel rail first disconnect the battery cable before detaching the fuel supply tube quick connect coupling installation at the fuel rail location. After disconnecting the fuel rail pressure and temperature sensor connector and vacuum tube the service proceeds with removing its four fuel injector electrical connectors. Disassemble the radio capacitor by removing its nut before separating its wire harness retainers from both the valve cover stud bolt and two fuelling rail pin-type retainers. The two fuel rail stud bolts require removal before taking out the fuel rail assembly with its injectors. The mechanics need to remove and discard eight O-ring seals which belong to fuel injector. During installation use new O-ring seals created from fuel-resistant material which need clean engine oil lubrication. The fuel rail and injectors can be reinstalled as one unit after installing both retainer clips to the four fuel injectors that must be carefully tightened with fuel rail stud bolts at 23 Nm (17 lb-ft). The installation requires reconnecting both pin-type wire harness retainers to the fuel rail while securing the wire harness retainer at the valve cover stud bolt. Position the radio capacitor before installing the nut which should be tightened to 10 Nm (89 lb-in). Repeatedly connect the four fuel injector electrical connectors and the vacuum tube and electrical connector for the fuel rail pressure and temperature sensor as well as the fuel supply tube quick connect coupling at the fuel rail, and the battery ground cable.
