Turns out there was this metal rod connecting that hose to the hose coming out from the bottom of the charcoal canister, i knew it was there cause i saw the rod dangling and it had the other torn part of the hose with the clamp on it, yet i looked up hose diagrams and it shows that its supposed to be open to let air flow. So whats the hose (shown above) go to?
Edit: Sorry for the huge pic, but it doesnt expand further so guess its alright.
