The liquid pump includes a strainer housing, a pump housing assembly secured to the strainer housing, and a lock ring fastened to the pump housing assembly. The pump housing assembly includes an outlet that is rotatable between a first position and a second position and further includes an annular protuberance defining an inlet.

A clip is positioned within the chamber and releasably secures the annular protuberance so as to inhibit inadvertent disengagement of the strainer housing from the pump housing assembly.
