A method for operating a fuel tank device for a motor vehicle, with a fuel tank to which a tank ventilation line is assigned, and with a tank shutoff valve for adjusting a flow-through cross section of the tank ventilation line is disclosed. The method includes impinging the tank shutoff valve with a first electric voltage for adjusting a first flow-through cross-section of the tank ventilation line and impinging the tank shutoff valve with a second electric voltage for adjusting a second flow-through cross section of the tank ventilation line; when switching from the first flow-through cross section to the second flow-through cross section and/or vice versa, impinging the tank shutoff valve for a defined transition time period with an .transition voltage which lies between the first voltage and the second voltage.
