In the representative system for continuous fuel injection described in the specification, an air pump withdraws air from the air intake line of a gasoline engine and a fuel pump delivers fuel from a fuel tank through a fuel pressure regulator to a metering device which supplies fuel as a function of the operating state of the internal combustion engine, the air withdrawn from the intake line being mixed with the fuel from the metering device. The fuel pressure regulator returns excess fuel to the fuel tank through a return line and, in order provide fast response to sudden load changes, a valve device, which can be adjusted as a function of the variations in the rate of application of the load on the internal combustion engine, is provided in the return line. The valve device is controlled according to changes in the vacuum in the intake line downstream from a butterfly valve.
