Fuel Line Compression Seals
Thanks to Marianna2003 for the part numbers for the seals.
I pulled the fuel line and was having a bear of a time getting the old hardened seals out. It was cold here this morning 48F
. I used my cigarette lighter to heat them up and that made it much easier to dig them out.
No more air intrusion.

You can see the line here near the alternator and the other hard line going from the filterhead to the IP.

These are what you need.
The ones I needed were the 5/16 ones.

Alternate parts
I can confirm that the seal kits that are advertised for the later model super duties, on Amazon and at the parts stores, do contain seals that will work in a pinch. I used the 5/16 seal on the IP and one of the 1/4 seals on the filter head and both sealed fine.
Dorman - OE Solutions Fuel Line Seal Kit 904-497 from advance is what I used. Really overpriced but if you are in a jam it'll get you home.
on Amazon they are advertised as fuel line seal kit for 99-03 7.3L power stroke.
I ordered the Russ kit to permanently fix the issue.
Hope this helps someone in the future!
