Abstract
In a tank system, a venting line () connects the fuel tank to an activated carbon filter, and a recirculating line () opens into a filler head (). In order to prevent the penetration of liquid fuel into the activated carbon filter, to permit the seal to be checked by applying a partial vacuum and to provide a filler head which can be manufactured inexpensively, an insertion body () is provided which forms a funnel () which is adjoined by a neck () which accommodates the fuel nozzle, which insertion body () has, in addition to the neck (), two vertical blind holes (), open at the bottom, and a transverse duct () which connects the latter, wherein the first blind hole () is connected to the recirculating line (), and a float (), which clears or closes off the connection to the transverse duct (), is guided in the second blind hole ().
