Abstract
A method of attaching a member to the interior of a blow-molded plastic fuel tank wall. The wall is molded from a pliable parison. An inwardly directed projection is formed integral with the wall. The projection has an inner surface and an outer surface. The outer surface forms a cavity receiving a core. The core is inserted within the cavity while the parison is partially pliable and fuzes to the wall. The projection is inserted through an aperture in the member and heated. The softened projection is squashed to secure the member to the wall.
