Where can I find the vents?

Are the charcoal cannisters even used with a Weber Carb?

The biggest thing that confused me when I installed my new carb is how all the emissions gear fits together. The weber carb uses none of it, while the stock carb was a rat's nest of vacuum lines. I left most of it intact. I've wanted to rip stuff out and replace my EGR with a block plate, but I'm afraid to mess anything up.
