My fuel pressure runs at about 11-12 psi at idle and sometimes drops to 9 when im getting on the throttle... is that a good psi to be running at? and if not how can i fix it? thanks, Awall

 

what's it at WOT(wide open throtle) i think 10psi is to low, but ya might want a 2ed opinion im runnin 14 1/2 psi on a fairly new oem carter LP

 

WOT it drops to about 9 and then i payed closer attention to it today and it idles at 12.... how can i raise my pressure?

 

with a new LP

 

such as a FASS!

anybody running a holly LP out there? I am sure he would like to hear one of you guys chime in.

try doing a search on holly or holley,you should get enough reading for a few days,theres a few options,running one with your stocker or without and theres diferent ways to wire one also,do a search

 

Just curious if that is pre or post filter.

If it's post filter and you're seeing 12 idle & 9 WOT, that is fine. From your sig, it looks like you don't need more pressure anyway. You'll just be wasting your money.
