Hydraulic system problems ('85 5000 turbo)

Without being an expert on this particular system, I would have to say 
my first suspect here is a lot of air still in the system.  It probably 
moves around, and ends up cavitating the pump while its running, 
killing, or at least randomizing, your pressure and assist.

I do believe I have read here that bleeding the system is a complex 
process (but that might have been the cooling system!).

I don't know if you need to elevate one end of the car at all, but I'm 
sure you have to turn the steering (with system running) from lock to 
lock several times.

Looking at it, you might be able to see where the high points, etc., are 
and determine the best way to make sure it is air-free.
