Fuel pressure too high?

I have a converted TPI car... it's got a holley vac secondary 600cfm and an airtex pump. The pump puts out 9psi and I have a holley regulator set to 5 1/2 psi

for some reason - and this happened with 2 carbs, both of which were set right - the fuel seems to leak out of the boosters as soon as the pump comes on.. is my fuel pressure set too high or are there other issues?
