So I got rid of the not so reliable low fuel pressure warning light system that was giving me some false alarms or so I thought. Anyway I installed a Stewart Warner mechanical F/P guage this evening piped in off the schrader on the injection pump. Now this is what sucks, I am only getting 6psi at idle and it drops right to 0 at WOT. I just installed a new lift pump and put in a new fuel filter about 2 or 3 weeks ago. So What are you guys getting for psi off the stock lift pump in the stock location? I'm thinking maybe this Lift pump is a dud.:CRY:

I also forgot to mention I just picked up a Hypertech programmer and have it set on stage 2. Could that affect my fuel pressure reading?
