Abstract: A fuel filler door module for installation in a motor vehicle is provided with a trough body that can be placed in a vehicle body along with a fuel filler door pivoted to the trough body. The trough body exhibits an axial through opening for accommodating a fuel filler neck, and a radially outwardly projecting fastening edge for attachment to the motor vehicle body.

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.

At least one passage is defined in the locking bracket for facilitating insertion of a closure device into the fuel filler tube end. At least one anti-removal structure on the closure device passes through the at least one passage during insertion of the closure device. The at least one anti-removal structure precludes removal of the closure device after insertion of the closure device, and rotation of the closure device from a first rotational position relative to the locking bracket to a second rotational position. First and second anti-rotation structures extending from the closure device engage first and second ends of the locking bracket to prevent further rotation of the closure device.

A fuel filler structure is equipped with a damper on the near side of a flapper valve in the insertion direction of a fuel nozzle. When the flapper valve rotates to an open position, the damper does not act on the flapper valve, and when the flapper valve rotates to a closed position, the damper acts on the flapper valve.
