So I have the guts removed from the Evap case & want to remove it from the firewall. I can't remember.... Can I unhook the blend/routing door cables & the case can come out or was there more behind the dash w/hard connections? When I did this before, i worked inside to out because I was doing dash work as the priority. This one is engine compartment concerns so if I don't have to do the interior side it's fewer parts I have to find storage space for.
