  Q: How to service the fuel rail with speed control on Mercury Cougar?

  A: The fuel rail service process with speed control should start by subtracting fuel system pressure. The first step requires removing the outlet tube and resonator from the air cleaner and disconnecting both fuel supply and return pipe spring lock couplings. Afterward remove the fuel supply and return hose clamp followed by unconnecting the vacuum hose from the Fuel Pressure Regulator. Begin by detaching the Accelerator Cable retaining clip. Then remove the accelerator cable from its bracket and disconnect the speed control cable which can be removed easily by detaching the cable while pushing the retaining clip to release the cable length. Before unscrewing the solenoid's electrical connector you must remove its connector grommet from the engine cover along with the fuel injector electrical connectors. Move the fuel injection harness onto one side before removing the fuel injection supply manifold assembly. Install a new fuel injector lower O-ring seal that needs lubrication with clean engine oil such as XO-10W30-QSP or DSP until Ford specification WSSM2C-153-H equivalent is met prior to reinstalling the parts with the reverse installation order.
