摘要： An apparatus for supplying fuel in a fuel tank to an engine through a diaphragm type carburetor includes a fuel pump and an exhaust passage. The fuel pump includes a suction valve and a discharge valve and is driven by pulsation pressure caused by rotation of an engine. The fuel pump has a discharge port connected with a fuel inlet of the carburetor. At least one of the suction valve and the discharge valve of the fuel pump is so located as to be immersed in fuel of the same level as that of the fuel tank. The exhaust passage has one end communicating with a position between the fuel inlet of the carburetor and a diaphragm chamber and the other end communicating with the fuel tank.
