I have an 08 Dakota Sport with the 3.7 v6 and I am at my wits end trying to track down this problem. This weekend I dropped the gas tank to check all the lines and see nothing that looks bad under there. Changed the gas cap when I first got the code after tightening the old one didn't do it and there are really no rubber lines just all hard plastic. Any ideas? I really don't want to go through changing line after line lol.
Thanks in advance

 

Boogerchaser,

I believe some of the possible causes for the codes you are drawing could be related to an evaporative purge system leak and loose or missing fuel filler cap or seal.
