A side feed fuel pump with a tube for fixing a fuel filter is developed in that the tube is formed as a portion of an overall housing for jointly enclosing a pump section and a motor section for driving the pump section. The tube that projects laterally from the side feed fuel pump is formed of the overall housing that jointly encloses both the pump section and the motor section. Inner space of the tube forms an intake port, and the intake port communicates a side intake passage formed in the pump casing with an exterior of the fuel pump. A fuel filter can be easily attached to the tube. The tube may be formed by pressing metal plate or integrally molded with a main portion of the overall housing by resin material.
