<p>A fuel supply system for a general purpose internal combustion engine is equipped with a sub-fuel tank 64 that retains gasoline fuel supplied from a main fuel tank 14 and houses the high-pressure pump 66 in its interior. In other words, the pump 66 is immersed in the gasoline fuel retained in the tank 64, so that if an air pocket should occur in the fuel supply pipe between the main fuel tank 14 and pump 66, the air will be discharged from the sub-fuel tank 64 to the exterior through a fuel return pipe 84 etc., thereby ensuring that the pump 66 does not suck in air. Since fuel injectors 50 can therefore inject gasoline fuel immediately, starting performance is enhanced.</p> |
