Abstract: A filling pipe for a fuel tank comprises a housing which has, on its inner circumference, a number of inwardly directed threaded segments and at least one vertical indentation, the upper part of the housing has segmented threaded parts for screwing a closure cap therein, and its lower part, which is contracted to the diameter of the filling pipe, contains an insert. The insert has, on its outer circumference, a number of outwardly directed threaded segments and two outwardly directed lugs, the segments together with the inwardly directed threaded segments of the housing holding the insert in the longitudinal direction, and the lugs together with the at least one indentation form a safeguard against twisting.

Abstract: A tank cap has a cap part, a filler neck for receiving a refueling nozzle wherein the neck can be closed by the cap part via a rotary closure having at least two seals arranged on the cap part and active between the cap part and the neck. The sealing surfaces on the neck are provided behind a raised region of a protuberance and below at least one projection.

Abstract: A filler pipe for the fuel tank of a motor vehicle having an internally located closure flap which closes a filling aperture at the end region of an internally located housing part made from plastic and can be brought into its open position by insertion of a fuel-pump nozzle in order to fill the fuel tank. An elastomeric seal is arranged on the housing part acting between the housing part and the closure flap. The seal is applied to a seal support which is connected to the plastic housing to provide a seal both relative to the closure flap and relative to the housing part.
