There's nothing in there (according to a VW mechanic friend I trust) . 
It's a noise supressor. If it's gone, the little hiss you hear the fuel 
pump do when you turn the key will become a whine. That's all. It's 
purely asthetic, to keep people from being annoyed (like anyone could 
ever be annoyed w/ a VW!!!) -T
