mine is like the one on the right... I bet they removed the screw hose ridge parts for the hoses.

One looks like it is designed to be mounted the opposite direction of the other.

The pumps are essentially the same. The one with the screw in bushings on the hose connections is the original pump, our P/N 685001, that we used for many years. The one with the cast in ridges is our P/N 685001-1 is our current pump that went into production in 2007 or 2008. Besides the cast in hose retainers it has a different cam on the inside that increases the pumping capacity. They both use the same impeller and gasket.

thanks engine nut .great info . is the cam the piece that is removable in the older pump by removing the small screw ? i noticed on the newer one there is no small screw. i did not take the time to look inside my new one that closely to see if the cam is still removable. is it or is it cast into the housing now.

cheers thanks for the info .

On the original pump, the cam was removable. I believe you are correct. The cam is pert of the pump housing casting now and is not removable.
