Abstract
In a method for operating a fuel system of an internal combustion engine, the fuel system has a fuel tank and a ventilation device, which has at least one vent valve, for ventilating the fuel tank. The magnitude of deformation caused by an internal pressure of the fuel tank of a deformation zone of the fuel tank is ascertained and the vent valve is opened when the magnitude of deformation exceeds a limit value.
