Abstract: A strainer for a fuel pump according to the present invention includes: a communicating pipe including a flow path formed to communicate with a fuel inlet of the fuel pump; a filter including an internal space in which a fuel flows and coupled to the communicating pipe so that the internal space communicates with the communicating pipe; and a rib disposed in the filter and coupled to the communicating pipe, in which the filter includes a first filtering portion extending in a length direction with respect to the communicating pipe, a connecting portion extending in a width direction at an edge of the first filtering portion, and a second filtering portion extending in the length direction at the connecting portion and spaced apart from the first filtering portion in the width direction. Therefore, the strainer may have a relatively large filtering area and a small size.

Abstract: The present disclosure relates to a fuel pump module, and more particularly, to a fuel pump module including a flange module and a reservoir module, in which when a fuel delivery pipe for supplying filtered fuel from the reservoir module to the flange module is coupled to the reservoir module, since the fuel deliver pipe may be coupled to the reservoir module to a desired position in an axial direction and to be prevented from rotating in an axial direction, the fuel delivery pipe may be prevented from interfering with a guide rod connecting the flange module and the reservoir module in a vertical direction, thereby not only preventing the occurrence of fire, but also increasing a common use rate of the reservoir module.
