。 In a percolation prevention device for a float chamber of a carburetor to which fuel is supplied using a diaphragm fuel pump, the diaphragm chamber of the diaphragm fuel pump is provided with a valve mechanism for sucking outside air and an air outlet. a pump chamber; an air flow path that communicates the air outlet with a space above the fuel liquid level of the float chamber; and a negative pressure pipe that communicates the space above the fuel liquid level with a vent lily portion of the carburetor. The vaporization is characterized in that the outside air that has been sucked into the pump chamber and pressurized is blown out from the air flow path onto the fuel liquid level in the float chamber, and further the outside air is sucked from the negative pressure pipe to the bench lily section. Percolation prevention device in the float chamber.
