Put a new BG fuel regulator on the car and I can not get the pressure below 12 pounds. What started this problem was I had a fuel pump problem that the pump was running at full pressure and the regulator and gages were peged. I change the fuel pump and that was the main issue with the way to much pressure.Stuck relief valve. Question does the ball inside of the regulator seat against the fitting in main in port in the bottom of the regulator or against the inside tower part of the regulator? Its a 2 port BG tower style regulator. Yes I am running the motor when I am setting the pressure.
