Abstract
An attachment is fixed to a fuel tank made of a synthetic resin, and is formed of a primary molding portion and a hydrocarbon barrier layer. The primary molding portion is formed of a first material capable being welded to the fuel tank, and includes a hollow section to be inserted into fuel tank, and a flange formed on the hollow section to be connected to an outer surface of the fuel tank. The hollow section has a plurality of holes for allowing a molten resin material to flow therethrough when formed. The hydrocarbon barrier layer has a property of preventing permeation of hydrocarbon. The hydrocarbon barrier layer is formed on at least a part of an inner periphery of the cylinder section. A connection section is formed at the hollow section to have another member thereon.
