Fuel Pressure?

I know it has been discussed a million times and Im sorry, but i cant find the post on fuel pressure range. I have seen people say 75-80 on the high side but cant find what pressure to not go below. Im idleing at 50 psi. I havent had a chance to drive it yet to see about a pressure drop though. (Just got it installed and Ive been up since 4 am. I know Im a sissy!!!!) Does this sound right or too low for idle. thanks in advance. Dustin

Yep acceptable range is 45 to 80 psi. Most of us try to keep it above 50 at WOT and between 62 and 75 at idle.

I would recommend you do the blue spring upgrade to the FPR.
