TC25 power beyond port

[JC26SWO]

I purchased a third function hydraulic kit for my TC25 tractor with a 7308 loader. I've searched through the threads and have not found anything conclusive about which line is the power beyond port on my tractor. I'm brand-new to the forums and couldn't get a photo to attach. There's seven lines attached to the loader valve. three of them go to a small square block behind the quick-connect ports next to the engine. The loader valve cast iron block has the ports identified, but the PB line could either be the "top left" (looking toward the back of the tractor from the right side, and has white/gray tape on it, and was identified in an old thread as a potential candidate,) or it could be the only line attached to the "side" of the loader valve (and has red tape on it). The top left line has a "P" stamped next to it, so I'm thinking the PB port is the one on the side. What gave me pause is that the hydraulic hose that came in the kit is not long enough, to reach the loader valve, from where their third function valve is instructed to be mounted. When I called the company, they said this kit has been manufactured for a long time an no one has called about the hose being too short.
Some of the older forums indicate this isn't a new question, but I couldn't find a clear answer. Thanks for the help!

Welcome John, I just installed one on my Boomer 50 and the line that goes from block to your three point lift is the one your looking for. The hose that goes from third function remote to three point under seat was too short and didn't have correct adapter and they said the same thing that no one else had problems. Had to have a new hose made and had a hydraulic supply make me a adapter, they are British pipe thread. So take the steel line that goes from block to three point out, run hose from block to third function valve and run second hose from third function valve to three point valve which should be located under seat. Was rather simple when had correct parts. Hope all goes well and enjoy when completed

If what Longshot is suggesting does not work, consider this approach.
If your new valve has a power beyond port install it before the loader valve and not after it.
In other words the new valve becomes the feed for the loader valve through its power beyond port.

Thank you for the replies. I apologize for the delay in a response - work got in the way of replying in a timely manner! I think I'm on the right track with this extra information here... I thought I had the instructions puzzled out when I ran into the too-short hose. I sure appreciate the help!
