For all you pundit's my original design was not done this way. Secondly the switch helps to unload the pump and fluid back into the tank when the loader is not used for some time.
Lionel was free to make changes to my design as they wished to facilitate production. They produced my design @ 99% I originally used 5/32 hose from pump to boom and a reduction barb from tank to pump. However my "Quick Fix" works well.
