OK, what a PITA putting this fuel pressure regulator in!!! What should I set it at? I set it at 40 with the vaccum line off. When I put it back on, it drops to 30. Should I readjust it with the vaccum on? Thanks!!

Set with the vacume off and leave it there. The vacume adjust the fuel pressure proportionally to the RPM's of the engine, at WOT you have no vacume so you get full fuel pressure.
