Abstract

See full text

A fuel pump unit includes a suction filter and a fuel pump. The fuel pump includes: a rotatable shaft placed along a rotational axis; a rotor portion that rotates in response to rotation of the rotatable shaft; a suction hole portion, through which the fuel is suctioned into an inside of a rotor receiving chamber; and an outer peripheral wall that surrounds the suction hole portion. The suction filter includes: a filter element that filters the fuel and conducts the filtered fuel into an inside space; and a columnar hole portion having an inner peripheral wall, while the outer peripheral wall and the inner peripheral wall are fitted with each other, so that the columnar hole portion communicates between the inside space and the suction hole portion. The columnar hole portion is placed such that the rotational axis extends on an inner side of the inner peripheral wall.
