Abstract

The invention relates to a fuel tank having at least one filler pipe (2) enclosing a refueling duct (13), at least one operational venting valve (11), at least one refueling venting valve (8) and at least one venting line (9), which is connected to a filler head (3) of the filler pipe (2). The filler head (3) comprises a valve, which when refueling closes a flow path from the venting line (9) into the refueling duct (13). One of outstanding features of the fuel tank is that the venting line (9) 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 (10) connected to the filler head (3).
