Abstract:
1. A tank arrangement, having a fuel tank having a plurality of fuel chambers and configured as a saddle tank; a tank installation unit arranged in the fuel tank; a fuel pump element located in a first chamber of the plurality of fuel chambers and set up to provide fuel from the tank arrangement to a fuel consumer; a first pump unit arranged in the first chamber and configured as a suction jet pump, the pump unit operatively connected to the fuel pump element and set up to deliver fuel from the first chamber into the tank installation unit; a second pump unit arranged in a second chamber of the plurality of fuel chambers; a tank level sensor located in the second chamber, the fuel pump element controllable as a function of a signal of the tank level sensor; and a pressure regulating element functionally arranged between the fuel pump element and the second pump unit, wherein the pressure regulating element is configured as a mechanical pressure regulator, and wherein the fuel pump element is actuatable in such a way that the system pressure is increased, starting from a system pressure, at which the pressure regulating element is closed, until the pressure regulating element is open such that fuel is delivered by the second pump unit, resulting in a drop in the tank level, which can be detected using the tank level sensor.
