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.
