Abstract

A plug neck for a filler neck of a motor vehicle has exchanging means for refueling-venting adaptation to different refueling devices. In the case of a refueling device which removes gases from a refueling channel by suction, a compensation chamber is connected permanently to the refueling channel via a connecting channel. For adaptation to a refueling device without suction removal, the connecting channel is closed and the vent valve is provided with a cap which has a connection neck for a line leading to an activated carbon filter. This allows tool costs for producing the plug neck to be kept particularly low.
