Abstract

The description relates to a fuel tank serving to provide fuel to the internal combustion engine of a motor vehicle. The fuel tank contains a vessel arranged therein, from which vessel a delivery unit pumps fuel to the internal combustion engine of a motor vehicle and in which are arranged a plurality of jet pumps for filling the vessel, which jet pumps are connected to a line system which is charged with fuel by the delivery unit, the mixing tubes of the jet pumps opening out into the vessel. A reliable filling of the vessel with fuel is ensured in spite of the compact construction even when the tank is almost empty and under unfavorable operating conditions in that jet pumps connected in parallel to the line system are arranged at a common structural member and in that a suction line leads to each mixing tube, the openings of these suction lines remote of the structural member being situated in the tank at a distance from one another.
