When you use a GM pump with a Mustang II rack the steering is too sensitive so Speedway Motors offers a replacement valve to lower the boost of the GM pump. If someone (not me) is sharp on the workings of a p/s pump maybe they would know if a spring that goes behind the piston is available that would drop the pressure. This would be an easy fix and it wouldn't harm any of the original parts so the process could be reversed.
This was discussed a while back and I've tried a search,without success.
The Speedway one AFAIK is an adjustable unit much like the brake balance valves you can buy.
If i'm not mistaken there is a fitting you can buy that reduces the actual pump itself and is at a fixed pressure.
I'm sure another 'bolter used this although I can't remember who.
I'm interested in this as I was going to ask the exact same question today!
Hopefully the 'bolter in question will see this thread and chime in.
Maybe I've looked at the wrong part,coilover,but if you know of such a thing do you have the link?
Thanks
Jock.
