A method for operating a fuel system for an internal combustion engine operated with fuel gas. The fuel system has at least one electrically actuated shutoff valve (4) and at least one electrically operated heating device (14, 16). The operating method includes: generating a signal to turn on the heating device (14, 16) when the internal combustion engine is turned on; determining a heating demand (υreference) of the fuel system when the heating device (14, 16) is turned on; and depending on the heating demand (υreference) of the fuel system, determining a delay time between the time the heating device (14, 16) is turned on and the time the shutoff valve (4) is opened. The heating demand (υreference) can be a function of a temperature (Tengine coolant) of the engine and/or a temperature (Thydraulic fluid) independent of the engine and/or the current (Iheating) flowing through the heating device.
