Re: Power Steering issues

The CPP kit that uses the GM box shouldn't need a flow restriction.

You are using a good quality and preferably Genuine GM power steering fluid? From working on a lot of power steering boxes they don't do their best with ATF.

Just thinking what did the pump come off if you used a donor pump? Some GM pumps came with different pressure ratings depending on the vehicle they were originally assemble for. The old style from the 70's probably won't be an issue but if you have one of the newer type II with remote reservoir it could be a low pressure unit for a rack or a variable pressure unit for a performance car that reduces pressure at speed to control the twitchy steering thing.
