If you tried to use a conventional power steering pump to power a hydro boost system you will undoubtedly not find it satisfactory. You'll need the whole system, rather than cobbling parts not designed for the purpose together.

Done properly the hydro boost system works like it should, but all the pieces need to be in place. As far as trouble with them, and trouble shooting them, complexity, not seeing any of these things in my own cars/trucks, or customer cars/trucks I've worked on. Reliability has to be right up there with a hammer, and an anvil. 3 hoses doesn't confuse me, nor do I consider that complex............

As I stated, a new car that came with it is not a good comparison, because it was all designed to work together.

The complexity comes in trying to get exactly what you touched on, calibration, valving, etc. Troubleshooting comes in when it's not right, calibration or whatever.

Never commented on reliability, but it's a good point. The units are usually sourced from OE applications, so suspect the units themselves are reliable.
