Abstract
The invention relates to a fuel supply device pertaining to an internal combustion engine. Said fuel supply device has a regulating device comprising a first regulator, which is provided with at least one integral part and which produces, in a first mode of operation, a regulating signal for a volume flow control valve, and a second regulator that produces a regulating signal for an electromechanical pressure regulator in a second mode of operation. In the first mode of operation, an error in the fuel supply device is identified according to the integral part of the first regulator. In the second mode of operation, an error in the fuel supply device is identified according to a detected fuel pressure and the regulating signal for the electromechanical pressure regulator.
