moog5050 Posted August 7, 2008 Report Share Posted August 7, 2008 I recently installed a fuel pressure gauge and my pressure runs from 65 to 72 on regular driving. Its an 03 return style with stock intank pump and a magnuson in line booster pump. I changed both the pump and regulator but the pressure stays the same. This seems a bit high. Should I be concerned? I was thinking about doing a dual in-tank walboro set up, but don't want to do it if its not needed. Quote Link to comment Share on other sites More sharing options...

moog5050 Posted August 7, 2008 Author Report Share Posted August 7, 2008 Tune seems OK. My wideband shows 11.5 at WOT with supercharger. I am just not certain whether this is an indication of a problem. Quote Link to comment Share on other sites More sharing options...
Simon Posted August 10, 2008 Report Share Posted August 10, 2008 i have an aeromotive regulator with 255 lph in tank and the pressure is always at 58- 60. if it's where you says it is i wouldn't be concerned. As long as it doesn't go low when doing a wot run and it does not pop off you fuel rails lol. Quote Link to comment Share on other sites More sharing options...
04CHASE Posted August 11, 2008 Report Share Posted August 11, 2008 just watch for drop seems a bit high but better high than low as long as your afr is consistant. try a different guage to if you have access to a manual guage that would be nice to see, your guage may just read high.
