PURPOSE: A connector for a fuel tank is provided to effectively reduce leakage of fuel evaporation gas of fuel in a fuel tank from the connector portion. CONSTITUTION: A connector for a fuel tank to connect a fuel tank(B) and a pipe(C) in communicating fashion includes a gas barrier member(10) made of a synthetic resin with a gas barrier property. The gas barrier member includes a tubular portion(11) and a flanged portion(12) provided on a peripheral side of the tubular portion with a greater side than an opening(Ba) of the fuel tank(B). The gas barrier member is made of polybutylene terephthalate, polyphenylene sulfide, a liquid crystal polymer, aliphatic polyketone, aromatic polyamide, a blended polymer of an ethylene-vinyl alcohol copolymer and high-density polyethylene, a blended polymer of polyamide and polyethylene, a blended polymer of polymer of polyamide and high-density polyethylene, or polyethylene terephthalate. |
