Title: fuel press.
Post by: jjpp250 on July 15, 2008, 08:14:23 PM

 how many psi should i have at the carb.  It is on a 455  with a holley classic blue electric ( i belive they are 60-70gph)and it is feeding a holley 850 dp.  I just installed a new regulator, going to tune it good tommorow, i just want a good number to start with, i dont want to fool with it on the water, it is just to hard to get to

Typical fuel pressure is between 5-7 psi, if it is a spring type reg. should be pretty stable at all rpm.
