I guess I'm confused -- the big red and blue Holley gerotor
pumps are LOUD! and have about 7 - 10 psi output pressure -- they're
designed to replace the old mechanical pump and to drive a carb.
I have one of those in series before the high-pressure Carter
pump on my ProJection.  The smaller Carter in-line pump that
comes with the ProJection is designed to feed into a 15 - 20 psi
regulator and makes no noticeable noise above the normal cabin
noise of my Bronco (I've had two of the Carter pumps -- thought
the first was bad when it was a clogged pickup sock in the tank).
