Abstract
A fuel supply apparatus is adapted to control a pump which discharges fuel from a tank to a fuel passage, thereby regulating the pressure of fuel to be supplied to an engine. The tank includes a plurality of storage chambers, in a specific one of which the pump is placed. A part of the fuel discharged to the fuel passage is returned to the specific storage chamber through a branch passage. A storage chamber other than the specific storage chamber is in communication with the branch passage through a communication passage. A jet pump is operated to transfer the fuel from the storage chamber other than the specific storage chamber to the specific storage chamber through the communication passage by the action of the fuel flowing through the branch passage. An electronic control unit (ECU) controls an electromagnetic valve disposed in the branch passage to regulate the quantity of return flow, thereby delivering the fuel in a quantity corresponding to a consumption quantity of fuel to be sequentially consumed in the engine, to the engine through the communication passage.
