ABSTRACT:
Disclosed is a device for supplying fuel from the fuel tank to the carburetor in an internal combustion engine, which device includes a fuel pump adapted for forcibly supplying the necessary amount of fuel into the carburetor and for recirculating an extra amount of fuel to the fuel tank. A heat pipe is, on one end thereof, arranged to touch the fuel in the carburetor and, on the other end thereof, to touch the recirculated fuel. The heat pipe operates to remove the heat of the hot fuel in the carburetor and to transfer the heat to the recirculated cool fuel. Thus the evaporation of the fuel in the carburetor can be effectively prevented.
