PURPOSE:To prevent the vapor lock by upwardly arranging the opened port part of a return pipe connected to a carburetor inside a fuel reservoir and connecting a circulation pipe for returning vapor to a fuel tank, over the return pipe. CONSTITUTION:The fuel in a fuel tank 1 is introduced from a connection port 6 into the fuel reservoir 5 of a vapor separator 4 through a pipe 11 and sent into a carburetor 2 by a fuel pump 3 through a pipe 12 from the connection port 7 of the fuel reservoir 5. The fuel generated in vapor form through the warming in the carburetor 2 is discharged into the fuel reservoir 5 from the opened port 8a of a return pipe 8, and accumulated into the upper part of the fuel reservoir 5, and the vapor is separated and returned into a fuel tank 1 through a circulation pipe 9, and thus circulation is performed.
