Zusammenfassung:In a fuel system of an internal combustion engine, a low-pressure delivery unit for the fuel, at least indirectly delivers fuel to at least one low-pressure injection device. The fuel system further provides a high-pressure delivery unit, which has a drive region and a delivery region and at least indirectly delivers fuel to at least one high-pressure injection device. According to the invention, the fuel is first delivered by the low-pressure delivery unit to the drive region of the high-pressure delivery unit and from there onward to the low-pressure injection device and/or to the delivery region of the high-pressure delivery unit.
