Go see the dealer there was a TSB and at one time the one way flapper located at he end of the filler tube was replaced. Gas tank end. I've heard some had the whole fill tubed replaced. Somebody's idea to save a penny. The plastic it was made out of swelled and the flapper stuck, thus the filling problem. TSB 98-15-3
