What are you trying to accomplish ?? I can give you a quick run-down as to what constitutes a simple hydraulic system...First a reservoir with an outlet and return , A non pressured fill cap , and a suction filter of sorts[usually a screened covered cylindrical shape that screens the oil of large solids] to prevent large solids from tearing up a pump..Next is a pump..Larger fitting size is the suction side..Always use a hose thats marked suction hose..Hydraulic hoses used here are known to seperate the inner lining from the inner steel wire and cause suction flow problems..The smaller fitting is the pressure side out..Always use at least 2 wire hoses for pressure applications..Pumps come in different rotations[ clockwise or counterclockwise]..Next is the hydraulic line from the pump outlet to the control valve..The control valve should be marked inlet and outlet..Also the control valve should contain a system relief to protect the pump from overpressuring..Connect the other 2 or more lines to the individual functions..Then the return hose from the control valve to the reservoir..[I would install a return filter on the return line to the reservoir to filter out any impurities before they get dumped into the reservoir]..

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
