My 240 was an incomplete and partly dismantled car so as I'm putting it back together I'm running across some questions.
After mounting the fuel tank I realised there's this small tube (4mm diameter?) next to the filler neck. Does this connect to a tube or is this just left open?

Thanks for any input!

 

That's the breather tube for the tank, connect a tube to it and route it so the fumes can vent away from the trunk (boot) _ to the outside.

 

Thanks for your reply!
