Another Weber Question????

Can someone tell me what connects to this fitting??? Its a weber 32/36. The instructions says its a float bowl vent fitting but where does it hook up to???

i couldnt tell ya..

you could put a mini lil filter on it.

if you kept the charcoal canister under the hood for fuel vapor's connect it to that, otherwise take out the nipple and install a plug

Is there any advantage to having it vented?
