PROBLEM TO BE SOLVED: To efficiently discharge generated vapor and cool a fuel in a fuel feeding device including a plunger pump. SOLUTION: The fuel feeding device includes a plunger 112, a tube 111 housing the plunger 112 reciprocatably and demarcating a pump chamber P, an intake valve 123 allowing suction of the fuel, and a discharge valve 127 allowing discharge of the fuel. A fuel reservoir 150 including a filter 152 is provided integrally upstream of the intake valve 123 in relation to the plunger pump 110 sucking and discharging the fuel, and a discharge passage 170a communicating the outlet 121a of the tube 111 and the fuel reservoir 150 is provided, thereby discharging leaking fuel or generated vapor towards the fuel reservoir 150. Thus, the vapor can be discharged efficiently, and the fuel in the fuel reservoir can be cooled by the vapor. COPYRIGHT: (C)2005,JPO&NCIPI
