とを特徴とする内燃機関の燃料供給装置。[Claims for Utility Model Registration] Fuel supply for an internal combustion engine in which fuel is pumped to the internal combustion engine by a turbine-type fuel pump from a fuel tank in which a part of the bottom wall protrudes upward to form two independent fuel reservoirs. In the apparatus, two pump parts, a main and a sub pump part, each consisting of a suction port, a fuel flow path, and a discharge port are independently provided on the same outer periphery of an impeller provided in the turbine-type fuel pump, and the sub pump part to transfer fuel from one of the two fuel reservoir spaces to the other, and the main pump section sucks fuel from the fuel reservoir space on the side into which fuel is sent by the sub pump section, thereby producing an internal combustion engine. 1. A fuel supply device for an internal combustion engine, characterized in that it is configured to supply fuel to
