Does anyone know hydraulics

I take it that the new line has a y in it and feeds two cylinders. And that the other lever in the back is Raising and lowering the arms.

If so do you have down pressure on the arms?
Yes there is a y in each of the 4 hoses. The other side that had 2 hoses is for bucket tilt and back and works as it should. The one closest to the camera with the 1 new hose only has fluid out the front one when pushing the lever forward and pulling the valve back there is no fluid out the back post/new hose.
