Not a picture of my Kombi, but helps point out what I'm talking about. That circular hole that gives access to the Fuel filler hose. I have seen it with a cover in Kombi's and without. Mine is currently missing a cover. I'm not sure if this is something that has been missing for a while or only just recently. It's just an area I have never paid to much attention to. Either way I've never thought of it's purpose and looking at the big hole makes me worried if it is an important item that I am missing, or if I am missing anything at all and it is meant to be uncovered. Can any body shed some light on what the deal is? If I was to take a guess I would say that it is meant to have a cover which goes towards being a barrier between hot engine and fuel hose / tank.
