Does anyone know what the regulator is pre set at when you take it out of the box on the holley fuel pressure regulator? I have read you should set it to around 7psi. I didnt want to start the car with 14 psi going into the carb if the regulator wasnt preset. Thanks, Dave

I've been using those things for years.
All of them I've ever had would be 6-7 psi out of the box.
When putting on car to fire -up just hook fuel pressure gauge to it for makin' real sure..........
