Fuel feeding system for vehicle

A fuel feeding system for a vehicle, comprising:

• a fuel tank having an inside space which is divided into a first portion in which a reservoir is installed and a second portion;
• and
• a subsidiary jet pump installed in the second portion of the inside space of the fuel tank, the subsidiary jet pump pumping out fuel pressurized by a fuel pump and causing the fuel, stored in the second portion of the inside space of the fuel tank, to enter the reservoir using a pressure difference generated when the fuel is pumped out,
• wherein the subsidiary jet pump includes:
• a nozzle unit having an inlet portion through which the fuel is introduced into the nozzle unit by the fuel pump and an injection portion which communicates with the inlet portion and through which the fuel is injected;
• and
• a diffuser unit which is structured to surround the injection portion, with a suction channel disposed between the injection portion and the diffuser unit and having a suction hole and a discharge hole at a first end and a second end of the suction channel, respectively, the diffuser unit being structured to cause fuel suctioned through the suction hole and fuel discharged through the discharge hole to flow substantially in a same direction.
