Abstract: The invention relates to an extrusion blow-molded filling tube (1) made of plastic for a motor vehicle fuel tank, which consists of a multilayered coextrudate and has mouth areas (7) at each end, which each have a flange and/or faces (8) provided for welding to connecting parts. The inventive filling tube (1) is characterized in that the two mouth areas (7), which are located at different ends, are provided with a defined wall thickness and a defined inside diameter.

Abstract: A device for fixing a functional component within a fuel tank that makes use of an opening in the tank wall of the fuel tank. The device comprises at least one connecting element for receiving the functional component, with the connecting element being latched in an opening in the tank body wall, in a position of passing therethrough. The opening is sealingly closed at the outside of the tank by a closure member or a cover cap or a connection portion can be fitted to the opening for the connection thereto of a device intended to communicate with the tank interior.

The opening is sealingly closed at the outside of the tank by a closure member or a cover cap or a connection portion can be fitted to the opening for the connection thereto of a device intended to communicate with the tank interior.

Abstract: A fuel tank for a motor vehicle has at least one reservoir which is arranged within the fuel tank, and a fuel pump associated with the reservoir. A filling conduit for filling the tank with fuel is of such a design that at least a partial flow of the fuel flowing through the filling conduit can be fed directly to the reservoir. The filling conduit opens at its delivery end into an open catch receptacle which communicates with the reservoir by way of at least one discharge.
