Fuel pressure is very important if running Weber carbs. Unfortunately, most fuel pressure regulators aren't very good, especially at the low PSI that your Weber wants. Regulators made in Italy by Malpassi are renowned as some of the best regulators made which is why Redline recommends them when needed on a Weber set-up. Unlike cheaper regulators, Malpassis don't choke down the flow when the pressure is adjusted down - so you get a stable feeding pressure with a high flow under any load conditions. This regulator is adjustable from 1.5 to 20 psi. Certainly not cheap but quality never is.
