The fuel vapors then flow into the intake pipe by virtue of the intake pipe vacuum and assisted by the vapor pressure of the fuel in the fuel tank and then burned in at least one combustion space of the internal combustion engine. The method according to the invention for ventilating a fuel system is intended for use in motor vehicles.
