The locations that sucked air was the quick disco on top of the tank and at the fuel pump inlet quick disco.The only fix is 5/16 hose and worm gear clamps to replace the quick discos which pretty much takes care of the air in the line.
I looked tonight and I know the 6.0 has the QD's at the HFCM. Since I haven't seen the top of the tank, I assume it has one there also for the fuel feed.
Oh and uh oh: I drained my aux fuel tank filter tonight and got fuel that looks like #2 or #3 out of the aux fuel filter feeding the OEM tank (see link below). Fortunately, I got #1 out of the HFCM. Pics to follow as soon as my daughter gets home.

$25 worth of fuel filters no longer seem so expensive, no?
Stay tuned for my pics.

ETA, ok here are pics of the fuel. The aux fuel tank filter drained fuel is on the left, HFCM drained fuel on the right. The only difference between the two pics is the first one has a shop light behind it.
ETA#2: The left fuel now looks exactly like the #3 sample on the DTS site. The color of the fuel is less orange and there is a definite dirt line at the bottom of the sample bottle.
