This 756 tractor has left hyd connectors out the back and steel tubing going forward on both sides of the seat.
The left rear tubing is a one piece setup with both tubes going backward into a solid block that looks like a check valve (but isn't). Then the left front tubing connects to this block on the side and goes forward along the seat.
I understand what you are saying about the right valve connecting to the port side into the casting then out the back. It makes more sense than trying to use the same pipes to connect the second valve to the port side. Once the first valve is plumbed in, it will operate two more rear remotes and it also connects to the right front hyd outlets.
I have picts of the connections on a 706 that uses tubes as you describe (I have those) but uses two seperate tubes from the left valve out the rear. Some tractors have hyd tubes or hoses exiting out the front of the seat platform that come up under or near the center steering column.
I'm hoping an Farmall expert will chime in, that is farmilar with the one piece steel tube setup with both valve connection tubes exiting out the back into a solid block that then hyd connectors can be mounted.
I need to know if this is modified to fit? Thanks for your help,
