Fuel lines are also loosing pressure when the truck has been off for a while. I can let it sit for an hour and a half and it'll take 2-3 seconds+ to crank vs firing right up normally.

Your truck needs a new FPR, that is the first indication that it is going, or is bad.

you didn't answer my question though, do you still run the voltage booster, that you said you were using, in that thread? why "were" you running it at that time?

so besides the fuel pump install, what else would affect a fuel pressure drop like this? no one seems to have too many other ideas, besides guage malfunctioning....... which doesn't line up, because i've been showing lean on the o2's. and fuel pressure regulators...... which doesn't seem to be an option.
What else is there?????????????

No, I am not running the booster. The booster was being tested on the STOCK PUMP. I am running the same exact set up as you for a fuel pump.
