<P>PROBLEM TO BE SOLVED: To obtain a vehicle fuel supply device that can prevent back-flow from a vapor exhaust hole, with a simple configuration. <P>SOLUTION: The device includes a flange mounted to an upper opening of a fuel tank, a fuel pump for sucking the fuel which is inside the fuel tank via a strainer and increasing a fuel pressure and discharging the fuel, a high-pressure filter for filtering the fuel discharged from the fuel pump, and a pressure regulator for maintaining the pressure of the fuel filtered by the high pressure filter in a predetermined range. A member for preventing, when a pressure loss of the strainer increases, the fuel inside the fuel tank from flowing into a pump flow path where the pressure of fuel is increased is provided in a bottom portion of the fuel pump including the vapor exhaust hole formed in the pump flow path. <P>COPYRIGHT: (C)2013,JPO&INPIT |
