Are you talking about an older pump, i.e. 60s-70s?

I modified my 71 pump per one of the MOPAR mags.
It entails pulling out the valve on the back of the pump and adding a shim washer, (I used a brass washer that I had to file the O.D. a little) .030" thick if I remember correctly.

Haven't tried it yet, but it is supposed to reduce the boost to more acceptable levels.
It really is what MOPAR did by using the same pumps on smaller cars, (Valiant, Dart) with different shim packages.

I'll try to find out which mag it was, I have it somewhere.

I used the power steering pump that was on the 5.7 engine. No problems with excessive pressure
