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!
If there is no boost, the fuel pressure should stay at 7psi, right? why does it drop to 4psi?
I hope SMRE crew will help you!
Should I set my fuel pressure at 7psi with or without vacuum?
I have set mine whitout. When I put on the vacuum and cruiseing my fuel pressure drops to 4psi.
If you are talking about your fuel regulator, it should not be connected to boost, not vacumn. As your boost rises, your fuel pressure should rise accordingly, generally 1 lb fuel pressure to 1 lb boost
Boost or vacum?Quote:
