Alright so I got the charcoal can off.. I am stumped by how it works now, or if I'm missing a hose. So on the end of the canister there's an elbow with a hose that connects to that, that's all fine and dandy.. Then there's a little black box mounted on the canister. It says "to canister" with an arrow pointing to a hose that goes into a T where it meets up with the charcoal canister and an electrical sensor. Now my concern is that there is a nipple on the other side of the black box where a hose looks like it should go, before the "to canister" sign. There was no hose connected and I looked around and didn't see one. It has no screen or anything on it so it's easily sucking in dirt and debris.. As far as I know I thought this emissions system was a closed off thing so now I'm very confused.. Is something missing?
