A fuel feeding system for a vehicle may include a fuel tank and a subsidiary jet pump. The fuel tank is divided into a first portion in which a reservoir is installed and a second portion in which the subsidiary jet pump is installed. The subsidiary jet pump pumps out fuel pressurized by a fuel pump and causes the fuel in the second portion of the fuel tank to enter the reservoir using a pressure difference generated during pumping of the fuel. The subsidiary jet pump includes a nozzle unit and a diffuser unit. The diffuser unit surrounds an injection portion of the nozzle unit with a suction channel disposed therebetween. The suction channel has a suction hole and a discharge hole and is structured to cause fuel suctioned through the suction hole and fuel discharged through the discharge hole to flow in the same direction.
