Yeah you can't get more removed than that. I'm surprised they took them all the way out since they are part of the emission control system. We don't have emission testing here but I know other states do.
I moved my canister in preparation for the undervan storage.
On the top of the canister is a electrically operated purge valve that, when open, takes the fumes from the canister and directs them to the air intake.
That line should definitely be blanked off.
