ABSTRACT:
A fuel supply system of an internal combustion engine includes, a fuel return branch connection positioned downstream of a fuel filter. The branch connection returns part of the fuel which passed the fuel filter back into the fuel tank. An end of the fuel return connection is extended to the bottom of the fuel tank. A throttle part for controlling returned fuel flow is positioned in the branch connection. Because part of fuel which passed the fuel filter is returned into the fuel tank, fuel in the fuel tank is repeatedly filtered by the fuel filter. Thus, removal of dust in the fuel is improved and total fuel flow passing through the fuel pump is increased. This improves cooling of the fuel pump and thus helps prevent vapor generation while also improving durability of the pump.
