ABSTRACT:
A fuel pump for an internal combustion engine including a casing wherein partition walls divide the upper space of said casing into a fuel drawing chamber receiving fuel from a fuel tank, a fuel chamber discharging the fuel to a carburetor and a vapor separating chamber communicating with the fuel tank. A space between the fuel chamber and the vapor separating chamber enables the communication of the fuel chamber with the vapor separating chamber, so that a large portion of the vapor produced in the fuel chamber removes to the vapor separating chamber and can be returned to the fuel tank, with the result that fuel substantially free from vapor can be supplied to the carburetor.
