An unloading valve is disclosed. A housing defines a primary and secondary pump inlets, and collective and bypass pump outlets. The housing defines a bypass seat. A tappet has first and second tappet ends longitudinally spaced by a tappet body. The tappet is configured for selective longitudinal reciprocal motion between first and second tappet positions. A tappet shoulder is located on an external surface of the tappet body for selective sealing engagement with the bypass seat to allow fluid flow in a bypass direction and resist fluid flow in a collection direction longitudinally opposite the bypass direction. The primary and secondary pump inlets are in fluid communication with the collective pump outlet for flow in the collection direction when the fluid pressure at the primary and secondary pump inlets combined is below a predetermined bypass pressure and the tappet is located in the first tappet position.
