2007 Ford Focus Fuel Rail Parts Q&A

• Q: How to ensure safety and proper procedure when servicing the fuel rail on 2007 Ford Focus?

  A: Avoid all open flames and smoking within proximity of fuel-related components when servicing the fuel rail because highly flammable vapors are present. Disconnection of any fuel line requires applying fuel pressure relief procedures to avoid personal injury. Start by taking the quick release coupling from the fuel rail then put the fuel tube aside. The first step should be to disconnect the battery ground cable and after that remove the four fuel injector electrical connectors. The maintenance process requires disconnecting both the fuel rail pressure and temperature sensor electrical connector and the vacuum tube. Secure the fuel rail and injectors by using two bolts that require 25 Nm (18 lb-ft) torque when reinstalling these components. New fuel-resistant O-rings should be used instead of standard O-rings because they prevent fuel system leaks but old O-rings must not be reused. Take off fuel injector protruding clips and separate the fuel injectors while disposing of the former O-ring seals if required. Use clean engine oil for lubricating new O-ring seals before reinstalling the parts through the reverse order of the removal process.
