Our QSC's are not
CR, CAPS pumps. QSC was the Industrial version of the on road ISC until they went to Tier 3 emissions in 2006-2007. ISC/QSC CAPS aren't terrible if you don't listen to mother Cummins on diagnosing them. They like to just replace the CAPS pump and charge about $6K.
25-40psi for a P7100, holley blue won't have crap for flow at 20psi. Need a better pump. My vote would be a mechanical pump, otherwise you're dumping one electronic wonder for an electric one that will die and leave you dead again.
I understand your application is stationary...hence why I gave the recommendation that your radiator should be fine.
