A tank system of a motor vehicle includes a volume modifying element, having a compensation volume, which is provided in the inner chamber of the fuel tank and which is used to equalize the vapor pressure. The compensation volume is connected to the surrounding area. The only connection between the volume modifying element and the surrounding area is formed by a storage unit of the gaseous fuel components and the inner chamber of the fuel tank is connected to the surrounding area by a valve unit. The valve unit is normally open when filling the fuel tank and when exceeding or falling below the pressure limits in the inner chamber of the tank, and is otherwise closed. The storage unit is connected to the valve unit. The volume modifying element and the valve unit are designed in such a way that vehicles which are parked for several days do not undergo diurnal losses due to changes in temperature of the surroundings, due to the fact that the vapor pressure equilibrium in the fuel tank can be maintained by the automatic supply and removal of ambient air in the, or from the, volume modifying element as long as the valve unit remains closed.
