The tank (100) has a gush wall bracket extending along an inner wall of a liquid tank shell (101) i.e. plastic mold part. A gush wall is provided in the gush wall bracket. The gush wall bracket connects the liquid tank shell with another liquid tank shell (109). The gush wall bracket is arranged in a pillared portion of the former liquid tank shell. Halt ribs stabilize the gush wall bracket. The former liquid tank shell and the gush wall bracket are formed by an injection molded part. An aperture is formed in the gush wall.
