The invention relates to an ICV structure of a fuel tank and a forming method of the fuel tank of the ICV structure. The ICV structure comprises a valve body. A check valve is connected with the lower end of the valve body, a hose connection end is arranged at the upper end of the valve body, the valve body is provided with a U-shaped groove, a welding surface is arranged on the valve body, and a convex welding line is arranged on the welding surface. By adopting the technical scheme, the special ICV structure and the wall of the fuel tank are connected after the fuel tank is pre-formed by adopting a special method in the blow molding process of the fuel tank, and thus the purposes of higher reliable performances of connection between the ICV and the fuel tank and lower hydrocarbon emissions are achieved.
