2009 Ford Focus Fuel Rail Parts Q&A

• Q: What safety precautions should be observed when servicing the fuel rail on 2009 Ford Focus?

  A: Safety measures should always be followed while servicing the fuel rail because it contains extremely combustible mixtures. Never use cigarettes or personal or open fire near fuel components since they can result in grave personal injuries. It is essential to drain fuel system pressure before separating fuel tubes because the system maintains high pressure levels when the engine is off. The removal of all fuel residue from the engine compartment will prevent engine ignition during operation. Personal electronic devices must stay away from any fuel-related components throughout their operation. Working on the Evaporative Emission system together with any fuel components requires full disconnect of the battery ground cable. The procedure for extractiing the fuel rail consists of two steps: first ventilate the fuel system, then unplug the battery ground cable. As the next step disconnect both the fuel tube-to-fuel rail quick connect coupling and the four fuel injector electrical connectors. Detach both bolts that stabilize the fuel rail and its mounted injectors. The installation procedure requires bolt torque to reach 25 Nm (18 lb-ft). Special fuel-resistant material must be used for new O-ring seals because regular O-rings can produce leaks and make it necessary to avoid old O-ring reinstallation. During removal process the fuel injector retaining clips together with fuel injectors are detached while discarding the previous O-ring seals. New O-ring seals receive oil lubrication before assembly following the removal method in reverse.
