Abstract
Disclosed is a fuel feed device of an internal combustion engine. The fuel supply conduit communicating the carburetor and the fuel tank is arranged in the carburetor for cooling the carburetor and for vaporizing the low boiling components in the fuel only when the temperature of the engine is higher than a predetermined level. The fuel flowing out from the fuel supply passage located in the carburetor is introduced into a low boiling component separator. In this separator, the low boiling components in the fuel are removed, and then the fuel consisting of the high boiling components is fed into the carburetor to prevent the occurrence of an abnormal fuel metering operation under a high-temperature condition.
