What exactly pressure do LS1's need fuel pressure at?

Those along with a nice fuel filter -- would that work for my fuel system for the LS1?
What pressure do I set it to?
Can I just put a fuel pressure gauge inline through a T to see what the pressure is?
that regulator looks like mine, but mine was about 130 and i got it from jegs. the pump...wow, $420+ for a pump?!?! just get a walbro 255lph to drop in the tank/cel, got mine for $99 off a LS1tech GP. it should need ~62-65psi continuously(especially upper rpms). i think ill set mine at ~65psi. you can test the pressure at the schrader valve on the end of the rail i believe.
Why does that pump flow a max of 45psi!?!?!? I can't find anything better. I need an inline as I'm doing a fuel cell setup, and don't want one in the tank -- do you have any other suggestions for an inline that would flow at 65 psi?
i think walbro makes a 155lph inline pump. redspeck_09 on here has one i think on his s-10.
The LS1 is supposed to be 58 lbs. For some reason these engines pick up a few extra ponies by dropping the pressure back to 56 lbs.
Thanks guys, between all of you, and a couple FSC buddys, i'm ditching this fuel cell and going back to the stocker tank. I have no plans to ever drop the truck on bags or anything, this is a strictly performance static drop truck. :thumb:
