ABSTRACT:
A devices for pumping fuel has at least one suction jet pump and a drive line, supplying the suction jet pump with fuel, that branches off from a pressure line leading to an internal combustion engine and that can be blocked off by means of a shutoff valve. By means of a shutoff valve, it is possible to switch off the suction jet pumps. The pressure of the pressure line acts on the shutoff valve in such a way that the shutoff valve closes at a pressure that is greater than or equal to a predetermined closing pressure.
