Quick question, what does this bit do?

Hi,

My father just asked me to look at his 2003 VW Polo and asked what this part is and if it should have a cover on it. While it looks familiar, I wasn't quite sure - can anyone clarify? - thanks.

Its the fuel filter, I'm not sure about a cover.

Ah thanks, I was going to guess that but didn't want to look stupid! Thanks for you help.
