ABSTRACT:
A connector for a fuel tank includes a flange portion, an outer connecting portion to be connected to a pipe member and an inner connecting portion to be inserted into a fuel tank through a connecting opening of the fuel tank. The inner connecting portion has an engaging portion to be engaged with an engaged portion provided to a member when the member is to be disposed in the fuel tank. The flange portion includes an outer flange member made of a synthetic resin same as that of an outer surface of the fuel tank, and an inner flange member made of a synthetic resin having a gas barrier property and a rigidity higher than that of the synthetic resin constituting the outer flange member. The inner connecting portion and the inner flange member are made of the same material.
