Hey folks! The TJ's throwing a code for a small evap link, I think it probably has something to do with the fuel filler neck having broken loose from the neck bezel. I've got a new neck bezel on the way, and I'll be doing a smoke leak test this week. Anyone have any ideas about what could have caused the break?

The new neck bezel won't do me any good if I don't solve whatever problem caused the break to begin with.

Also, thanks everybody in advance for all the help. My other thread about the steering gremlins has been very helpful.

I don't think so, but jeeps are new to me so I snapped some photos in case I'm misunderstanding what I'm looking at.

Lol thanks, yeah I'm still working on the evap leak too. I fixed it long enough to get it registered, but after I went off-roading it has returned as a large evap leak.

My P0456 popped up Friday. Put on a new MOPAR filler cap today and cleared it, so far it hasn't come back yet. The $30 fix never works for me, so I'm skeptical. Only time will tell I guess. Hope you can get yours tracked down!
