Been noticing that when I unscrew my gas cap there is some small bits of plastic that come out of the cap and fall below the filler mouth... been thinking this is not good... called my dealer and told him I think there may be a problem and I had better get it replace soon... He agreed and said just bring the old one in and he would replace it.... Well last night I was going to take it off and bring it in this morning to replace it.....Dugh!!! could not unscrew it... all the little ratchet teeth were gone from the last time I put it on.....So I got a large pair of channel locks and gripped the outside cap real good and got it off.... Just a heads up.... you see those little bits of plastic..... REPLACE......
