   I'm abit of a newbie when it comes to this stuff but.....
   
   I'm Trying to solve a rattling problem coming from the rear of my saxo.
   
   Came a across this, which is loose/ fixing clip broke. Sounds like it could create some noise.
   
   It sits on a 'ledge' on the fuel tank, underneith the rear axel, to the right.
   
   What isit? What does it do? Thanks

   It has a little metal ball in it.
   
   Also i doubt it would make much noise for you to notice over your exhaust, music etc.

   I think it's something to do with cutting the fuel supply off if you flipped the car on its roof ( I may be wrong but I'm sure I heard that somewhere )

   This. It's a ball inside which allows air into the tank by default in the correct orientation so you don't vacuum lock the fuel pump. If that valve/ball wasn't there if the car ever rolled petrol would piss out the breather.

   I know it's not broken, it was just loose and dangling freely.(which I thought would be the reason to the noise) It Looked like the mounting clip had snapped.
   
   
   Anyway thanks for the input guys
   I fixed this, but still have the rattle coming from the rear (I think)
   Only seems to rattle on slight acceleration....
   
   Really need to jack this up and have a proper look... Weather permitting
