| description | PROBLEM TO BE SOLVED: To improve fuel economy by restraining a steady delivery quantity of a fuel pump, in a fuel supply system having a jet pump for pumping up fuel of a fuel tank in a sub-tank. SOLUTION: This fuel supply system is provided for making the fuel in the fuel tank 11 flow in the sub-tank 11 by sucking the fuel in the jet pump 22, by generating negative pressure in the jet pump 22, by jetting the fuel returned in the fuel tank 11 via a return pipe 18 of a pressure regulator 17 arranged in the delivery side of the fuel pump 11, to an introducing port of the jet pump 22, by arranging the jet pump 22 for pumping up the fuel of the fuel tank 11 in the sub-tank 12. When increasingly correcting the delivery quantity of the fuel pump 14 for driving the jet pump 22, an increase quantity correction quantity for driving the jet pump 22 is set to 0 when a fuel level in the fuel tank 11 detected by a fuel level gauge 24 is a predetermined level or more.
