Apparently, the '08 Wrangler I bought "burps" gas when filling up. Seems there were several TSB's generated for various fixes at the dealer. My question is does Chrysler cover these "fixes" or is it out of pocket for me? Seems that fixes range from a valve, to a vapor canister to a new gas tank, or all the above. Has anyone through the fix for this and what was the cost -was it worth it?
