Claim:
A suction filter configured to be connected to a suction port of a fuel pump, comprising: a filter member configured to define an internal space; and a plurality of passage members at least partially disposed in the internal space, wherein each passage member has a fuel passage and at least one opening, the at least one opening of each passage member fluidly connecting the internal space of the filter member to the respective fuel passage and each fuel passage being configured to guide fuel from the internal space to a location external of the internal space of the filter member, and in a cross-sectional plane through each passage member and through the at least one opening taken perpendicular to a longitudinal direction of each passage member, a first position on an outer circumferential surface of each passage member in the cross-sectional plane, which said first position is closest to the filter member and is impermeable, is offset in a circumferential direction of the passage member from a second position on the outer circumferential surface in the cross-sectional plane where the at least one opening is formed.
