Time to install Fuel System?? TNT RELATED

I just got my transmission back in and downloaded the tnt and gave it a try.. I have gone all the way up and low as sw3. And tm3 timing2 rp2 wg was off on all levels i tried and now matter what when I get on it WOT from a roll or dead stop i drain the rail bad and get about 2 or 3 pops really quick and then i let out of it.. I got a quad gauge on the way. I want to see which is actually going out. I got a ad150 I am about to install.. Just haven't had the time. What yall think is going out? LP?? I can't see no more then 30 psi boost either. Is that normal or is fuel causeing that? Also when I am going down the road and get on it and if it doesn't pop the motor just doesn't rev hard like it should and the exhaust isn't deep and loud like it use to be.. Fuel problem??

Once you put on your AD150 I think you will be set. It definitly sounds like your not getting enough fuel to the CP3

Thats exactly what I figured it was.. Truck is just sluggish when you floor it and it pops.. Even when I turned the truck on stock it was still sluggish.. I think the stock lp is crapping out.. I hope thats what it is anyways!! Only a gauge will tell I guess.

Installed (had someone else do it - bad knee) AD150 and elimination kit...works awesome...quiet, 15-16psi...no worries...just follow the instructions on the draw straw section and you'll be good to go...can get to low fuel on overhead, low fuel light on, and guage on E....and it still shows 15psi...except when i lock up the brakes (it goes to 0 then, but doesnt stall or stumble)...

If you're careful you can get around the 1/4 tank issue. Just be sure to cut the line so that it has a small V notch in it. Sort of spring the line into place in the center of the tank.

I wouldn't eliminate the stock filter location. Theres a heater in there and any extra filtration can't hurt.

I can get way lower than 1/4 tank with mine but I usually am trying to get fuel by then anyway.

I only killed mine one time by running it out of fuel and it was when I installed the kit. I ran it way down before the install to help with handling it. I'd say I had about 5 gal in there.

After I did that I took the truck to town and back (~10 miles) and it did fine. What got me was when I stopped for a bridge replacement light at the bottom of a hill. Killed it right then. I drifted down into this guys driveway and as soon as it leveled out she fired right back. Luckily I was right across the road from the only gas station for 5 miles in either direction. That was the last time I filled up on LSD too.
