A plug ( ) for sealing a filler neck ( ) of a fuel tank has a cap ( ) which is dismountably attached to the end ( ) of the filler neck using a thread ( ) or bayonet, and a seal ( ) whose sealing surface ( ) faces a counter-sealing surface ( ) of the filler neck, whereby a ring-shaped molding ( ) is provided between the sealing surface and the counter-sealing surface. In order to minimize the amount of permeation, a sealing ring ( ) outside of the molding ( ) is provided, the sealing ring being made of an elastomer with high resistance to permeation, and the sealing surface ( ) and the counter-sealing surface ( ) create a narrow gap ( ) on the sealing ring ( ) side facing the molding ( ), this gap extending to the sealing ring ( ).

In motor vehicles with an onboard refueling vapor recovery (ORVR) system, a filling pipe with a reduced cross-section is provided. The pipe portion with reduced cross-sectional area has at least one longitudinally directed bead which gradually merges into the adjoining cylindrical regions to reduce flow resistance and prevent turbulent flow. The bead can be produced without impairing the strength of the filling pipe. When two or more beads are provided, they are preferably distributed equiangularly.
