Abstract
A fuel supply system for fuel supply of an internal combustion engine has a fuel supply container, a fuel supply unit having a pressure limiting valve providing an adjustable maximum pressure, a fuel supply conduit having a pressure regulating valve adjustable to an operational pressure for maintaining a regulated operational pressure in the fuel supply conduit, a fuel return conduit adapted to connect the internal combustion engine with the fuel supply container, and a delay valve associated with the pressure regulating valve for loading the fuel supply conduit with an initial pressure which is higher than an operational pressure.
