Service of the fuel rail starts with the removal of fuel system pressure from the system. Start the procedure by disconnecting the couplings that lock spring-loaded fuel supply and return pipes. Then separate the retaining clip from the fuel supply and return hose. To begin service of the fuel rail disconnect first the pressure regulator vacuum hose followed by
Accelerator Cable clip removal and finally remove the accelerator cable from the
Throttle Body. Begin by pulling out fuel injector electrical connector cables before taking off the fuel injection supply manifold assembly. To perform proper installation follow the guidelines to install a new fuel injector lower O-ring seal that requires lubrication with clean engine oil either XO-10W30-QSP or DSP or an equivalent product holding the Ford specification ESE-M2C-153-E. The installation ends by executing the reverse sequence of removal steps. Pay attention to fuel-related components because the vapors highly present in this area can ignite and cause serious personal injury.
