Abstract
A fuel injection system of an internal combustion engine includes a first and a second fuel pump, a leakage-prone volume flow regulating valve arranged in a fuel line between the first and the second fuel pump, and a control unit configured to actuate the first fuel pump as a function of a position of the leakage-prone volume flow regulating valve, such that the leakage-prone volume flow regulating valve serves as the sole actuating element for pressure regulation in the fuel injection system. An associated pressure regulating method is also disclosed.
