Patent ID: 8191568

Claim:
A fuel tank for a motor vehicle, which is formed by blow molding for attachment of a built-in part in an interior thereof, and of which an outer wall is composed of a synthetic resin and has an opening, wherein a functional part adapted to discharge fluid from the interior of the fuel tank or feed fluid therein is attached to the built-in part, a tube adapted to discharge fluid from the interior of the fuel tank or feed fluid therein is connected to said functional part, a tube connector is attached to an end of said tube, and a temporal holding connector is formed integrally with the built-in part such that said tube connector is attached to said temporal holding connector, and after blow molding, said tube connector is detached from said temporal holding connector and is attached to one of a tank cap adapted to close the opening of the fuel tank, and a fuel pump adapted to be assembled to the opening of the fuel tank, wherein the built-in part has a plurality of column members adapted to be fused to an inner surface of an outer wall of the fuel tank, thereby attaching the built-in part thereto, and beam members adapted to connect one of said column members integrally, and said functional part is attached to an upper part of said column member, and said temporal holding connector has a connecting section adapted to be connected to said beam member of the built-in part, and a tube attaching section in which said tube connector extending from said connecting section is adapted to be inserted, said tube connector has a seal ring in an interior thereof, and said temporal holding connector has a flat part in an outer surface of said tube attaching section in a longitudinal direction thereof along a parting line, which contacts said seal ring when said tube connector is attached to said temporal holding connector.
