Fluid exiting the hydro boost is low pressure iirc.
Been a while since I hooked it up in the Triumph. I remember my biggest issue there was cavitation - which I fixed by filling the reservoir from the bottom rather than the top
The other issue was flow. I had to get a better GM power steering pump to get enough flow to get both working. OP - Are you sure that’s not the issue?
