Abstract
A fuel pump is disclosed. The fuel pump includes a housing. Further, the fuel pump includes a rotatable pump shaft disposed within the housing. One end of the rotatable pump shaft is attachable to a gear. The housing also includes a retainer disposed within the housing and located about the pump shaft. The retainer includes a first rim and a second rim that are spaced apart from each other. The retainer also includes a side wall extending between the first and the second rims. Further, the side wall of the retainer defines a first volume and a second volume within the housing. The side wall of the retainer has a plurality of apertures configured to allow a fluid flow from the first volume to the second volume while retaining particulate contaminants larger than a size of the apertures within the first volume.
