    Fuel pressure OX66 250

    I know the fuel pressure should be 35 PSI but how long should the system hold that pressure after the engine is turned off. Also on the initial key on engine off when the fuel pump cycles should the pressure hold for a particular period of time before bleeding off? Thanks
