Thanks Mike. The OUT of the last valve in the series is returning to the filler tube of resevoir. These are older valves and I do not think they are power beyond capable valves. I am adding a return line filter. I do not understand why I am getting hydraulic oil out of the fill cap. Have I over filled the resevoir or am I pressurizing the resevoir? I have isolated the valves from the pump and resevoir. Engine was still bogging down when hydraulics on. I have since removed and inspected the pump. I have no reasonable way to remove the pressed aluminum gear cover within the pump body itself to inspect for blockage, which I believe is the problem. The pump does indeed still pump. The supply and pressure lines look ok and are not collapsed. Since replacing the pump the engine has not yet bogged but I have not run it a lot, waiting for hydraulic filter before running. I will replace the hydraulic oil again.
