[QUOTE="genie144, post: 68286, member: 431"] So I am [URL="http://powerstrokearmy.com/forums/showthread.php?t=2851"]redoing my fuel system [/URL]and finally have everything back together. I got the system all primed and the truck running and have some crazy fuel pressure. The gauge is pegged at 100psi. Now the only thing I changed is the entire pre-engine fuel routing (components are all the same). I believe the regulator was set at ~67psi before my project. What would be causing the high pressure? I need to add coolant so I didn't run the truck very long, but could air in the line cause high pressure? Should I burp the system (remove fuel line at regulator) before I start it next? If that doesn't work, just back out the pressure screw (that is just an alan key on top right?) on regulator all of the way and then move back in? Appreciate any input. Sam [/QUOTE]
