In a fuel container (1) for a motor vehicle having a plurality of chambers (2, 4), a suction jet pump (18, 19) with a filling level sensor (11, 12) is arranged in each of the individual chambers (2, 4). A valve (24, 25) is arranged in a propellant line (20, 21) leading to the suction jet pump (18, 19). When a chamber (2, 4) is virtually empty, the supply of fuel to the suction jet pump (18, 19) is disabled and an unnecessary movement of the fuel is thus avoided.

1. A fuel container for a motor vehicle having a plurality of chambers for collecting fuel, having a fuel feeding unit whose feeding capacity can be regulated, having suction jet pumps which are arranged in at least some of the chambers of the fuel container and have the purpose of feeding fuel to the feeding unit, having a propellant line which leads from the pressure side of the fuel feeding unit to each respective suction jet pump, having a filling level sensor for acquiring the filling level of fuel, and having a control unit for evaluating the signals of the filling level sensor and for actuating the feeding unit, characterized in that in each of a plurality of fuel collecting chambers there is arranged a filling level sensor for determining the filling level of fuel in each respective chamber, and in that means for reducing the feeding of fuel to the suction jet pump located in a virtually empty chamber are provided.2. The fuel container as claimed in claim 1, characterized in that the control unit is designed to reduce the feeding capacity of the feeding unit when a fuel chamber is virtually empty.3. The fuel container as claimed in claim 1 or 2, characterized in that a filling level sensor is arranged in each of the fuel chambers, and in that the filling level sensors are individually connected to the control unit.4. The fuel container as defined in claim 1, characterized in that a valve which can be switched as a function of the filling level in a chamber which contains a suction jet pump is arranged in the propellant line.5. The fuel container as defined in claim 4, characterized in that the valve is designed as a pressure-opening valve, and is closed in the home state below a predefined pressure in the propellant line.6. The fuel container as defined in claim 4 or 5, characterized in that the valve can be switched electrically and is connected to the control unit.7. The fuel container as defined in claim 4 or 5, characterized in that the valve can be switched by a float of the filling level sensor.
