This pump had a minor manufacturing defect.  The knotch that secures the plastic pump housing was missing on one side, so the housing rattles when the pump is running.  I can live with that, as it was so much cheaper to install (using a youtube video) than a service call!

Update-the pump failed over the weekend.  I am not happy with the prospect of replacing it again after a few months of operation.
