A method is provided for operating a device for filling a tank for storing fuel as condensed gas, in particular a cryotank, for a consumer that can be operated with cryogenically stored fuel, in particular an internal combustion engine of a motor vehicle. The tank includes a filling device for the cryogenically stored fuel, including at least one filling line and one extraction line for connecting to a filling device on a gas-station-side. The filling process is controlled in such a manner that in a first time period for cooling the tank, the condensed gas is introduced into the tank by way of the filling line, at least the large part is extracted again in the form of gas via the extraction line, and in a second subsequent time period, the tank is filled with condensed gas at the same time as at least the displaced gas is extracted. In a subsequent third time period, the filling line is closed and the extraction line is maintained open in order to guide the gas from the tank back until the pressure and/or the temperature in the tank is/are lowered to defined values.
