Abstract: The invention relates to a capless filler neck having an upper closure flap 2 and a lower closure flap 3, which are arranged in a pipe section 1. The two closure flaps 2, 3 must be able to seal independently of one another. In known capless filler necks, this has the effect that, when the filler pipe 4 of a fuel nozzle is still partially inserted, the lower closure flap 3 is already closed, whereas the user still has the impression that tank filling can be carried out. As a result, fuel collects between the two closure flaps 2, 3. The invention prevents this in that the lower closure flap 3 is opened or held open by the upper closure flap 2 or by an actuating element even when the filler pipe 4 is no longer in contact with the lower closure flap 2.

If the time t has elapsed without the fuel filler lid switch being manipulated again, the fuel filler lid is opened, determining that internal pressure in the fuel tank has decreased to a level predetermined to ensure that the fuel tank can be filled safely without fuel or fuel evaporative gas spouting from the fuel tank.
