HPCO on International 784

Power Beyond (HPCO) on International 784

So I installed a High Pressure Carry Over (HPCO) end plate to my S/A valve on my IH 784. Then I used an O-ring boss fitting with 3/4 BSP threads to interface to the port in this plate. I ran this line to IN port of an external hydraulic valve. The tank return from this external valve is routed to the 1 5/16 O-ring plug in the transmission housing.

My problem is that I have no pressure at the HPCO port. I stuck a gauge on there and nothing. My experience with HPCO plates is that they require a pressure carry over adapter or cartridge fitting. I have found none for this Kontak HPCO. Is that what I'm missing? If so, where can I find one?

For those daring to take on this challenge, here's a picture of the business end of my original end plate. The HPCO plate has a 3/4 BSP port in the center.

I'm really surprised parts for the Kontak valves are so rare. My Case IH 2255 loader also has a Kontak valve with the same style end plate. Why doesn't anyone talk about the power beyond adapter cartridge to go inside the 3/4 BSP port. I'm assuming that's what I need.
