ABSTRACT:
This disclosure relates to a fuel supply system for an internal combustion engine, wherein a suction type fuel supply system supplies fuel through a fuel pump to a carburetor which is located at a level higher than the fuel level of the main fuel tank. In one disclosed embodiment, a reserve fuel tank is provided on the line connecting the main fuel tank with the fuel pump, and the reserve tank is at a level higher than the carburetor and the fuel pump, the fuel outlet of the reserve tank is located at a level lower than the fuel inlet. According to an alternative embodiment, a fuel supply system is provided wherein a suction type fuel supply system supplies fuel through a fuel pump to a carburetor which is located at a level higher than the fuel level of the main fuel tank. The supply line between the fuel pump and the carburetor is branched and forms a return circuit leading to the upstream side of the fuel pump, and a reserve fuel tank is installed in the return circuit at a level above the carburetor and the fuel pump. A standby outlet connected to the upstream side of the reserve tank is provided at a level below the outlet of said reserve tank, and the flow through the inlet of the reserve tank and the standby outlet can be switched over from one to the other.
