sorry sous , I forgot to mention that I did that yesterday as well. I tried to line up the slots the best I could. It seems like the standpipe would go in no matter which way it was positioned like the slots wouldn't go down into the grooves of the bowl. I also checked the check valve by pushing down on the center of the standpipe . and it seem to be working properly. Should I take all the guts out of the check valve and try running it like that?
So, if you didn't have a fuel gauge you would not be able to tell a difference in the way the truck is running right?
What is the lowest PSI the pressure gets to in a towing or full throttle condition?
Are you using a 90 degree bend or reducer at all between the bowl and sensor?
I think that 45 PSI is the minimum that should be sustained, but could be wrong. I know Tugly has stated the PSI minimum many times, but I just don't have the time right now to look it up.
I really cannot think of anything else to look at. You could try doing a warranty claim on the sensor and see about getting a new one from AutoMeter. I know I had a problem with my sensor from ISSPro the first time around.
Grasping at straws here friend, and I don't know what else to ask about because you seem to have gone through the entire system already.

You could, but I don't think this is your problem. Baatzy had an issue where the slots were not matched up well and the truck would idle fine, but when fuel was called for the truck would fall on its face.

Crimp on the hard fuel line is normal. It is typically done for ease of installation, to keep the nut near the end of the line rather than sliding all over. Passenger side fuel line is the same. Not a worry, will not affect flow.
Is the fuel cap original? Maybe it requires a vented cap. Also on trucks with plastic tanks there is a vent hose that clips to the frame rail. The end has a plastic fitting that can become clogged. Just more straws to grasp at.
