UNIDENTIFIED PART. SHOULD IT STAY OR GO

[GAJ1]

What is this? I assume it's an expansion tank for the fuel system. Can i get rid of this from the rally car? I need to know before the rollcage goes in as the diagonal goes across this hole.

its a carbon canister for venting the feul system, fitted as its eu law that you cant vent it to the atmosphire. personally id out it but make sure the vent isnt inside the car to avoid the smells of petrol

not sure what the others do, but maybe fit a non return on it if needed??

Thanks for the replies. I will bin it and sort the vent as you have suggested

Says its an expansion tank.

Carbon canister is next to the engine on the nearside (or under the water header tank on an M3).

I would leave it, but what do I know? Perhaps it's just emissons bollocks?
