Ok, little help here. The other morning early I noticed my gas filler door was partially opened. The gas cap was on tight so I closed it and didnt think much more about it. Curiosity had me go out and check again. Now for the question. Is there a anti splash flap (?) that is or should be visable in the neck of the fill tube? Both our other GMs have them but there isnt one in the 2010 Nox. Thanks!
