Abstract
The invention relates to a fuel tank having at least one filler pipe () enclosing a refueling duct (), at least one operational venting valve (), at least one refueling venting valve () and at least one venting line (), which is connected to a filler head () of the filler pipe (). The filler head () comprises a valve, which when refueling closes a flow path from the venting line () into the refueling duct (). One of outstanding features of the fuel tank is that the venting line () is embodied as a collective venting line for the refueling and operational venting and that in any switching position of the valve it communicates with a downstream fuel vapor filter () connected to the filler head ().
