2007 Ford Explorer Sport Trac Fuel Rail Parts Questions & Experts Answers

• Q: What precautions should be taken when servicing the fuel rail to ensure safety and proper installation on 2007 Ford Explorer Sport Trac?

  A: A fuel rail can cause personal injury because its components contain highly flammable mixtures so personnel must never use open flames or smoke near them. Clear all fuel pressure before taking apart any fuel system components or disconnecting fuel lines because high pressure continues in the fuel system after the engine shut off. When you use the fuel rail to create leverage ensure safe handling that avoids possible damage to the rail. Before and during installation procedures always apply fuel operation materials to protect liquid and vapor access points against contaminations then remove protective elements prior to installation completion. Begin by disconnecting the spring lock coupling followed by removal of the intake manifold together with the fuel supply tube bracket bolt that requires torquing to 8 Nm (71 lb-in) when reinstalling. After disconnecting the fuel injector electrical connectors proceed to remove the fuel pressure and temperature sensor electrical and vacuum connectors. The assembly of fuel rail and injectors requires their bolts to be removed while the proper torque should reach 23 Nm (17 lb-ft) during reinstallation. Engine installation requires fresh O-ring seals of fuel-resistant material for the fuel injector-to-intake manifold connections and engine oil lubrication before installing them while omitting the use of previous O-rings to maintain leak prevention. Perform the reverse order of the removal process until installation is finished.
