In a method for the pressure regulation in a common rail fuel injection system of an internal combustion engine wherein pressurized fuel is supplied to the various combustion chambers of the engine via injectors under the control of an electronic control unit, a first actual control pressure is determined from a measured rail pressure and compared with a desired rail pressure in order to form a first control deviation, whereupon a volume flow depending on the first control deviation is determined and, from the measured rail pressure, a second actual rail pressure is determined using overridingly the second actual rail pressure for the calculation of the controller parts of the high pressure controller.
