I just installed an intense CAI and removed my evap canister, should i plug the two lines that were entering into the canister or should i connect them together ... not really sure what to do with them and dont really know to much about the evap system

you could make them into a u bend or add the evap back and merely relocate it.

Relocate it. I did.

You may find you'll need to extend the wires.

right now i completely removed it but i have the two lines just wide open laying there, is it really that big of a deal, whats the purpose of this thing anyway ?
just to reroute the gas fumes ?

Ummm.....see that big line? It goes to your gas tank. Now you're spewing fumes from your tank into your engine bay.

The evap system (recovery) evacuates fuel vapors from inside your motor and collects them in the charcoal canister, then purges it back to your fuel tank.

Relocate and reinstall it in a vertical position behind the headlight. Extend your wiring harness if you need to.
