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: A quick connector includes a housing having an insertion recess and a communication hole communicating with the insertion recess and formed in a direction perpendicular to the insertion recess, and a first fixing part having an arrest portion and an insertion guide protruding from the arrest portion in a direction toward an entrance of the insertion recess, wherein the arrest portion is inserted into the communication hole so that a lower end of the arrest portion is disposed in a position corresponding to the insertion recess, the first fixing part being coupled to the housing, so that the quick connector may be applied to a low-pressure side line in a fuel supply line of a vehicle, and since the quick connector has a simple structure, the quick connector may be easily manufactured and may be easily coupled and separated.
