Abstract: A motor vehicle tank including a fuel tank for storing a fuel and a withdrawal insert inserted at an opening in a wall of the fuel tank, and a method of manufacturing such a motor vehicle fuel tank. The motor vehicle tank includes a fuel tank for storing fuel, the fuel tank having a wall with an opening, a withdrawal insert member operable for inserting at the opening, and a flange plate fastened to the wall of the fuel tank in a region of the opening of the wall. The withdrawal insert member includes at least one supply line for withdrawing fuel from the fuel tank for a consumer, at least one return line for returning withdrawn fuel via the at least one supply line to the fuel tank, and a level sensor operable to determine a level of fuel in the fuel tank. The flange plate includes a flange plate opening in the region of the opening of the wall, with a thread of a bayonet fastener or a thread of a screw fastener on the end-face edge of the flange plate opening.

Abstract: A fuel tank for a motor vehicle. The fuel tank includes a tank having an external casing having an opening and a forming zone in a region about the opening, the forming zone having a first forming zone region that is deformed in comparison to a shape of the external casing surrounding the forming zone and a second forming zone region on a periphery of the opening that is deformed greater than the deformation in the first forming zone region. The fuel tank also includes a filler neck for filling the tank, the filler neck leading into an opening of the external casing and being welded to the external casing by way of a weld seam that is accessible from outside the tank, the filler neck in the region of the opening being deformed greater than the deformation than the deformation of the second forming zone region.

Abstract: A tank closure that includes a first tank closure member, a second tank closure member, and a bias member having a spring force to brace the second tank closure against the first tank closure member. The first tank closure member has a first stop member, while the second tank closure member has a second stop member. The second tank closure member is flexibly mounted in an axial direction relative to the first tank closure member, the second tank closure member. The second stop member, in a closed position of the tank closure, forms a mechanical stop relative to the first stop member to prevent axial movement of the second tank closure member relative to the first tank closure member against the spring force of the bias member.
