What are the fuel pressure spec's for a 2006 21V Launch with a 5.7L Fuel Injected Assault 325 engine?
I'm getting 50 when the key is turned on and 90 with the engine running.

Thanks, I'll go out and check that now. Is the regulator on the throttle body?
OK, I'm not seeing a pressure regulator. Checked both the rails, photos attached and the only fuel line I can find is from the fuel pump to the first rail and on to the second rail. There appears to be NO return line from the rails. There is a return line to the side of the fuel pump that goes back to the fuel tank. There is also something just above the tank return line with a nipple that is covered up (blocked). What could it be?

Ok, I have pulled the fuel pump, here is a photo. Hope I don't have to replace it.2012-01-22_17-02-15_310.jpg
Is the second photo the fuel regulator? 2012-01-22_18-13-26_404.jpg
Well that was the issue. Swapped the fuel reg out yesterday and the engine runs fine now.
