There are very few hours and very little wear on this system.
Upon inspection and clean up a couple of items were needed to restore the system to like new condition.
We replaced the bearings, valves, gaskets, o-rings, and gave it a fresh coat of paint.
The internal parts for both pumps were spotless, pictures were taken and are avaliable upon request.
