You've had more than your fair share of problems. I hope you get it resolved for good this time. Good luck

Well, reviving this one unfortunately... After 6 months/7k miles of having no issues, I pulled my Superchips and installed a Diablo. First turn of the ignition and the gas light came on and after a few key cycles the cel is back.
Coincidence? I'll report back once I figure out the culprit.
I have a 2013 Laramie 2500 with 38K miles. Drove from Alaska to Idaho pulling a travel trailer and arrived when it was 102 deg F. Gas cap light came on just before we arrived, then CEL shortly after. Saw on here where it said to change out the gas cap first, clear the codes, then go from there. Went to local parts store, they checked the error codes, and confirmed it was either a evaporative system leak or bad gas cap. Gas cap was $12 so figured I'd try that. Didn't work. They cleared the codes for me but they were back before I'd left their parking lot. Drove it for a week or so to see if anything would change then took it to local RAM dealer. They pulled the codes (same ones) and replaced the after-market cap with a Mopar OEM cap. Codes haven't come back on and I've driven it several 100 miles since then. MOPAR cap was $15. Visually, the two caps look similar but the seal in the after-market one is slightly smaller. RAM service advisor said this is happens regularly and made his pitch to me for buying OEM parts. I'm just an old farm boy who would occasionally lose the gas cap on the tractor after failing to put it back on after fueling, and just stuff a rag in the hole until it was convenient to go into to town and get another. Amazing how technology has to change our way of thinking....

Remembered I never came back to this thread to update the gas cap I used. Attached is the one I used and I've been running it for months now with no CEL popups. Again, the only thing that sucks is it isn't tethered.

Maybe, dunno, kinda sounds like U have done a lot. Maybe change Catch can hoses to better braided ones, and use "gm" clamps to attach, and see what happens, just thinking out loud.....Hmmm, not seen any catch cans with a "dipstick", that's different...
FITZ posted a while back on some steps also, U may want to look at those and make a decision...
PSSS: Get rid of the E85 cap and put on OEM one???
Since I have a MY 19, I haven't done much to engine area except exchange OEM for AEM air filter in box. I do plan on possibly getting a MOE's catch can in the future..(also bed cover/rug). But alas $$$$$$$$$. I just am not 100% sure the catch can venting is a problem to cause the CEL and light? Seems more like a vent/cap/canister issue,... But I am no mechanic, just turn wrenches on mower and MC. Have not done ne thing mechanical except changed out Interior LED which was a monster PITA for overhead. Good Luck with your issue.....
Sorry I didn’t read entire thread, I had a issue once with my 14,6.4 2500 where I had to buy fuel from some little **** gas mart. And 30 mins latter the gas cap light came on, we where on a trip so it didn’t take long for me to burn that fuel, but after that I filled up with premium from a quality fuel supplier and half a tank later the light went off, I asked the dealer and he said could of been poor fuel.. was it?? Was it not?? It’s a easy test to try. Try getting fuel from somewhere else and see if it helps, definitely won’t hurt the wallet like buying parts.
