A cover element and clamping ring are mountable on and sealable to close a tubular portion surrounding an access opening in a wall portion of a container of a fuel tank assembly for a motor vehicle. The tubular portion is contiguous with and projects outward from the wall portion, defines the opening in the wall portion, and has a contoured bead which projects radially outward from the projected end of the tubular portion. The cover element is demountably situated on the projected end of the tubular portion and is thereby removably situated over the opening in the container. A sealing ring is removably disposed between the cover element and the tubular portion of the container. The clamping ring is removably snapped onto the contoured bead of the tubular portion of the container. In such a configuration, the sealing ring is cooperatively clamped and sealingly disposed between the cover element, the tubular portion of the container, and the clamping ring whenever the clamping ring is snapped onto the contoured bead of the tubular portion of the container. In one embodiment, the cover element includes a fuel pump module with a conduit for transferring fuel from the container. In another embodiment, the cover element includes a filler pipe for transferring fuel into the container.
