Abstract: A return valve of a fuel feed system for a gas automobile is provided to prevent friction noise and vibrations from being generated when an opening and closing valve is raised and lowered in the return valve. A return valve of a fuel feed system for a gas automobile includes a fuel pump, and a multi valve(10). The fuel pump is installed in a fuel pump and inclined at about 35 degrees to pump fuel stored in the fuel tank. The multi valve supplies the fuel pumped by the fuel pump to an engine and re-introduces the fuel returned from the engine. The multi valve includes a base plate(11), and a valve block(12) protruded on the base plate. The valve block has a supply passage(13) and a return passage(14). A bolt-type nipple is coupled to a lower end of the return passage and guides the fuel to flow toward one side of the return path.
