To provide a fluid feeding system capable of improving the reliability by minimizing the increase in weight, miniaturizing and weight-saving thereof.

A fuel pump 2 is made a triple gear pump having a first pressurizing part 9 and a second pressurizing part 10. A flow control unit 3 is comprised of a first flow control unit 3a for feeding a fuel of a set flow out of a fuel delivered from the first pressurizing part 9 into a burner 5 with the excess returning into the inlet side, and a second flow unit 3b for feeding the fuel of the set flow out of the fuel delivered from second pressurizing part 10 into the burner with the excess returning into the inlet side. Further, the control unit 3 is provided with a first change-over valve 40a capable of unloading the first pressurizing part 9 while the first flow control unit 3a stops, and the second change-over valve 40b capable of unloading the second pressurizing part 10 while the second flow control unit 3b stops.
