BigCountry Posted May 27, 2009 Report Share Posted May 27, 2009 (edited) Just installed my Prosport Fuel pressure gauge and It's showing 66psi at idle and cruise, WOT at the top of 2nd (5800rpm) it drops to 62psi. Only mods are intake exhaust and a tune. Just wanted to get it hooked up to see what the stock pressure looked like before I start the transformation Just seems high to me.

Krambo Posted May 27, 2009 Report Share Posted May 27, 2009 Yea that is high for a returnless system. When the truck is off (no pressure) does the gauge go to "0"? Quote Link to comment Share on other sites More sharing options...

Well, It is on an ignition activated switch so when I turn the key on, the pump runs for a couple seconds and the gauge sits on about 64lbs. Then I crank it and it bumps up to 66-67lbs. Then acts as I said in my previous post. Quote Link to comment Share on other sites More sharing options...
