Well that isn't the setup I thought you had but that looks like the standard early GM pump that should put out plenty of pressure.

Unless one of your hose adapters has a restrictive orifice in it because it is the wrong fitting even though it has the correct threads I'm at a loss on this one.

Still I'd think that would work the opposite in that you would not have power assist at an idle or low speed and it would work better at higher speeds.

Have you got a part number on the pump or kit that one can research a bit?

Looking on the CPP site it looks like you have this steering box kit CPP5559PSK-OC Plus this pump. 19-6168SB-6P

This is off Ebay but if they included this flow control valve to compensate for a MII rack and pinion it might give the results that are causing the issues you are running into. https://www.ebay.com/itm/CPP-Power-S...4383.l4275.c10
