Abstract

In a fuel tank (1) for a motor vehicle, a cap (4) which closes off an installation opening (3) has a metal insert (11). The metal insert (11) has a pressure-exerting surface (13) which faces toward an edge (9) which laterally delimits the installation opening (3). This construction prevents settling of the material, which in the long term leads to leaks from the fuel tank (1).
