Fuel feeder for vehicle

Abstract

Abstract PURPOSE:To reduce the cost of a fuel feeder by providing an auxiliary pump which is operated by fluid energy of the fuel flowing through fuel return passage and by which the fuel at the second bottom portion of a fuel tank is transferred to the first bottom portion. CONSTITUTION:A main fuel pump 8 discharges the fuel near a first bottom portion 2 to a fuel discharge pipe 12 side by making a switch 33. About one ninth of the fuel in three-way joint 17 is fed to a jet pump 22 side and the remaining eight ninth is supplied to a vehicle engine 31. Thereby, negative pressure is generated by fuel injection from the nozzle of a jet pump 22 and therefore the fuel at a second bottom portion 3 side is transferred through a transferring pipe 24 to the first bottom portion 2 side.
