My Ford Ranger runs at 30-40 psi, now that you mention it (read that in the service manual once). Ok, NOW this is making some sense - I'd forgotten about that.
I remember the manual for my 74 Duster indicated that the pressure the pump delivered to the carb was to be 2-3 or 4-5 pounds - but fuel injection changed all that, didn't it?
Ok, I guess this DOES make sense, I was stuck in 1970's thinking.
