Abstract: A suction filter, through which fuel is suctioned into a suction port of a fuel pump after filtering the fuel in an inside of a fuel tank of a vehicle, includes a filter screen and a plurality of fuel stoppers. The filter screen is placed to cover an inside space, in which a negative suction pressure is exerted from the suction port. The filter screen includes a bottom wall that forms the inside space and is formed as a permeable wall, through which the fuel and air are permeable, and the filter screen filters the fuel permeated through the permeable wall. The fuel stoppers are arranged along the bottom wall from a side, at which the suction port is located, toward an away side, which is away from the suction port. The fuel stoppers extend toward the bottom wall in the inside space.

Abstract: A gasoline fuel supply system includes a feed pump part, an inline pump part, and a high-pressure pump part. The feed pump part includes a non-positive displacement electric pump, and pumps a gasoline fuel from a fuel tank and discharges at a feed pressure. The inline pump part includes a non-positive displacement mechanical pump, and pressurizes the gasoline fuel discharged from the feed pump part and discharges at a middle pressure. The high-pressure pump part includes a positive displacement mechanical pump, and pressurizes the gasoline fuel discharged from the inline pump part and discharges at a supply pressure to a fuel injection valve.
