04CHASE Posted January 27, 2007 Report Share Posted January 27, 2007 being a return you should see around 58-60 psi at idle and it should increase as you go wot being return the returnless guys including myself see 60 at idle and mine goes down to like 52 psi which is bad. this is why im redesigning my entire fuel system and going to a return set up with dual fuel pumps Quote Link to comment Share on other sites More sharing options...
Krambo Posted January 27, 2007 Report Share Posted January 27, 2007 I see mid 50's at idle and as I get into boost, I max at 63-64. I love the 03 return fuel system Quote Link to comment Share on other sites More sharing options...
