How to service and repair the fuel rail on a returnless fuel system on Mercury Cougar?

You should begin fuel rail servicing by releasing the fuel system of vehicles using returnless systems. First remove the air cleaner outlet tube together with the resonator before disconnecting the fuel supply line from the fuel injection supply manifold. Start by unclipping and removing the accelerator cable from its mounting bracket and then proceed with disconnection of the fuel pressure regulator elements which include its electrical components and vacuum routing. Vehicle speed control systems require the disconnect of speed control cables at the throttle body before pulling out the cable by pushing the retaining clip. As a next step disconnect each fuel injector electrical connector after positioning the wiring harness to one side then remove the fuel injection supply manifold. Reverse the uninstallation steps while using XO-10W30-QSP or DSP engine oil or equivalent Ford WSS-M2C-153-H specification to lubricate the lower O-ring seal. A quality new fuel injector lower O-ring seal should be installed for proper operation. Fuels and their vapors are dangerous because they easily combust at all times so handle all such components with caution to prevent personal harm.
