Title: Fuel PSI
Post by: Problem Child on June 21, 2016, 02:07:59 PM

I just changed out my fuel PSI regulator and lines and would like to know if anyone can tell me what fuel PSI I should be running.
It is  454 (467 its 60 over) with holley 750 double pumper.  I have been told 4 and as much as 9.  So what would you guys say it should be.

Thanks
