mines not a cali. Not the Cali Gasoline either as ive traveled many states and had the same problem. Hmm well the dealership may have replaced more than the aftermarket tank, its probably simply a valve that gets stuck. Someways to stop it is to stop fueling midway (atleast ive heard and I think its true). Give it a break and do it again, ive noticed it only mostly happens when I filled up alot of gas.
Yup mines an 05 and no longer under the 3 year warranty. Well I go through alot of forums and maybe I was talking about threads on there. But yea no ones come up with an exact answer, but the JKs also have this problem.
