Fuel 2-3 psi

Yes flow is more important than pressure to the CP3, hence the low pressure requirements. Too high of pressure can be hard on the FCA.

The factory filter cover starts to leak at about 30psi.

My truck runs great in the -20 to -30 range as well, not sure what that has to do with it? I run about 6-8 psi 90% of the time.

Saying it runs well out of spec is like saying 1600 hasn't melted a piston yet, so why go off of what is spec'd.

Not arguing, just putting the info out.

My truck is running great at about 19-20 at start up.

My FASS 95 with a Baldwin FWS and Donaldson FF pushes 8-9 in the winter and 11 when in the spring and summer. These numbers are after the filter.
