A tank system of a motor vehicle includes a volume-modifying element, which is provided in the interior of the fuel tank at least substantially above the liquid level and which is designed as a deformable bag, which forms a compensation volume connected to the environment, and includes a valve assembly, which closes under the control of a float during the filling of the fuel tank and thus brings about a maximum fill level in the fuel tank. A measure is provided for eliminating an effect of the volume-modifying element on the maximum fill level height. This measure can be that the volume-modifying element is arranged in the fuel tank such that, when the vehicle is standing on a horizontal surface, the top side of the volume-modifying element is not significantly above the fuel fill level at which the valve assembly closes in the vertical axis direction. Other measures include, for example, a controllable valve, which is provided in the connection between the compensation volume of the volume-modifying element and the environment and which is actuated in the closing direction when the fill level rising during the filling process has reached the maximum fill level height.
