Hydroboost problem

I only run hydroboost and no power steering.
Hydroboost adapted from a 2000 ish diesel ram.
I found that the hydroboost did not build enough pressure without power steering
I am about to try plugging the high pressure line from hydroboost to power steering and just run the return line from hydroboost.

I run electric power steering from a Nissan cube and installed a volvo electric pump for the hydroboost.
