I have trubble with my fuel pressure.
I set my fuel pressure to 7psi without vacum.
Put on the vacumhoose and it should drop to 4psi.
Under full gas it should be 12psi + my boost (10psi)
My problem is that I drop fuel pressure and boost.
I have tighten the belt and tried whitout surge valve.
Maybe I set my fuelpressure wrong.
How should I set it?
My vacuum from the regulator is under the carb as my surge valve.
Very greatful for help!
