As someone who has driven and serviced hundreds of cars and lt trucks I can make a few statements on the hydro boost sys used thru the 90s up to 2001. The units as used in most astro vans and gm c lt trk /vans are extremely durable. I recc you check the output pressure of the gm pump as compared to the packard unit used with the stock assist ram to see if the pressure output is the same or you may have reduced assist.
