As I said, I've got a regulator in-line at the carbs to drop it to ~3 PSI. The lowest pressure pump in the Gold-Flo line looks like it's 2.75-4 PSI, so you'd probably still want a regulator with that as you're targeting 2.5-3 for the Webers. The regulator also helps smooth out the fuel pulses, I'm sure.
I don't think those little disc regulators deal too well with too high an input pressure, but they'll easily step it down from 5 to 3 PSI.
