Hi, so I was cleaning out my tank and heard a noise rattling about, I manged to get out a small plastic thing....
Picture!
Could someone tell me what it is?? Cause Ive never had this before....

It's a widget! Keeps the petrol nice and frothy!!

It looks like a fairing rubber grommet of some sort. It shouldn't be in there.

Yeahhh...It's not gone back in.
currently on my desk as a pencil holder
