Infamous EVAP Codes
Still having the same EVAP codes coming across the dash.
1) Replaced gas cap with Mopar gas cap.
2) Replaced vapor canister purge valve.
3) Replaced vapor canister.
4) Replaced vapor leak detection pump.
5) Checked clamp on filler hose.
I have supposedly passed a smoke test, plus changed these items too and I’m still getting the codes and an occasional odor of gasoline when I turn my truck off.
What’s next guys??

There's a series of rubber junctions that are along the length of the hard evap line that runs back from the purge valve, they get dry and crack, you can replace them with same length pieces of fuel hose. I'd check those. There's also a 90 degree rubber elbow that connects a hard line to the top of the canister that can be problematic.

Called a shop that could do the smoke test. Quoted me around $120, and that’s even if they can’t locate the leak.
1) what’s the likelihood of not finding the leak?
2) if not detected, then what?

You are paying for their time/expertise. That's probably an hours labor or so. Pretty standard these days......
I am of the school of thought though, that I tell the tech the problem I am seeing, (your code) and what I have done to attempt to address it. Then I leave it to them to decide how to approach it. I don't know of anyone that likes being told how to do their job.
When I actually did this kind of thing for a living, customers that told me what to do, got exactly what they asked for, and when they were upset that their problem wasn't fixed, I simply told them "I did what you told me to." Then I would proceed to diagnosis, and give 'em a price to actually fix it.....

Fuel pump seal at the top of the tank.
I have an 02 dak that had the same thing, small evap leak which became a big evap leak and fuel flowing out of the pump seal. It needed a new pump and when it was swapped in, codes went away, leak went away.
