u may want to look into how much line pressure the regulator is having to try to hold back.call aeromotive and see how much,then look up holley and ask if regulator can hold pressure back.
i have a superflow(now called magna fuel) and they said their pumps have very high line pressure(think i remember about 24lbs pressure) and i found out hard way the cheapy holley regulator could not hold it.actually aeromotive said their regulators would be marginal.
