I don't know what the pressure is but these pumps to my knowledge almost never go out.

The mechanical 12 valve lift pump is very reliable and long lasting.
My 2500 has the original pump with 245k on it. The 3500's was replaced at 180k.

Pressure specs are 17-22psi at idle. 25-35 at 2500 rpm no load.
Loaded the pressure should never drop below 25 psi.
