    Q:
    How to remove and replace fuel injectors and Fuel Rail in Acura MDX? Posted by Peggy C.
    A:
    To replace the fuel pressure regulator, release fuel pressure and disconnect the battery, remove the engine cover, and disconnect the fuel injectors' electrical connectors. Disconnect the vacuum hose from the fuel pressure regulator and remove the fuel pulsation damper. Remove the fuel supply line banjo fitting and discard the old sealing washers. Disconnect the fuel return hose and the fuel supply hose. Remove each injector from the fuel rail and clean the fuel strainer. Install new cushion rings and O-rings on the injectors and insert the fuel strainer. Install new lower O-rings and insert each injector into the fuel rail.
