Thanks for the info JJ the only port marked has a p. It is a metal line on the right side of the valve. There is a metal line on the left side of the valve. Both of these lines go to right rear of the tractor in what I assume is the pump. The third metal line comes out of the left side of the valve in front of the other two lines. This line goes to middle right side of the tractor. All of the other lines go to cylinders on the fel. I don't know how to post photos or I would send you one. THANKS
