Beschreibung
Zusammenfassung:	Disclosed is an engine fuel supply apparatus which can be made smaller in size and in which the amount of fuel in an air-fuel mixture (13) can be increased with a fast response in correspondence with the operation of a throttle valve (23) when the engine (14) is accelerated rapidly. The fuel supply apparatus is provided with a fuel booster pump (16). A portion of an air-fuel mixture is introduced into a negative-pressure chamber (65) of the fuel booster pump via a negative-pressure chamber channel (38), and the fuel booster pump is actuated. The actuation forces air in a pump chamber (66) to flow into a pressure chamber (27), and fuel (12) in a fuel storage chamber (26) is temporarily supplied to a carburetor (11).
