understood its a bypass regulator, but the diagram shows me fuel wizzing by the carbs feed tubes at full pump pressure and the regulator is down wind. seems to defy physics to me.
like i said if the regulator has less restriction than the needle and seat then i can grasp the concept. i guess i'm just missing some pertinent information to be able to see how it is feasible. pump pressure is 14 psi... it is 14 psi at the carbs and doesn't look like it stops being 14 psi until it hits the regulator.

just can't come to grips with regulating line pressure after the device you are feeding from a constant pressure before the device, did i just say that?
thats deep......hehehehe
