A fuel pump includes a connecting pipe having an open end disposed at the lowest point in a pressure chamber supplied with fuel by a pressure valve. The connecting pipe is connected to a mixture-former and the pressure chamber has in its upper region a ball valve with a return line which leads to a fuel tank. The pressure chamber can have a cavity establishing the lowest region thereof, the open end of the connecting size being disposed in the cavity. A filter can surround the lower end of the pipe to filter the fuel supplied thereto.
