    3. Apply a light coat of spindle oil or gasoline on the place where the fuel delivery pipe contacts the O-ring.
    4. Push the fuel injector while turning it back and forth to install it in the fuel delivery pipe.
      NOTE:
      • Be careful not to twist the O-ring.
      • After installing the fuel injector, check that it turns smoothly. If not, reinstall it with a new O-ring.
