So I took the plastic skirt off from around the Gas fill tube and found 2 hoses one has a little cap that might have a spring in it I assume to let it breath the other that was without anything attached to it which doesn't make any sense because it allows dust to be sucked in I'm thinking there should be something like some type of a filter that should prevent dust from getting into that tube I've looked everywhere I found one video where the guy seems to have some type of a filter he pulled off there and cleaned but that was on a 2017 and mine is a 2005 am I correct and thinking there should be something other than just an open tube?
