Cambria Hydraulic Leak

If anyone is interested, I found the problem. On the side of the hydraulic pump, there is a set screw inside of a jam nut that is part of the relief valve. Red fluid was coming from this item. The jam nut was not tight, so I tightened it. The set screw controls the relief for hydraulic pressure. I found this while doing an internet search (http://www.hwhcorp.com/ml47649.pdf). I ran the levelers 4-5 times, and no fluid leaked over several hours. It had apparently leaked from day one because oil was all around the area of the pump for a foot or two.

Also, the filler cap was basically loose and was easy to spin either way.
