I recently had to replace my evap solenoid due to P1443 Code. It code came back so I replaced vac line before and the harder one going to the canister, my question is this. I can't seem to find anything online about one of the 2 3/4" vac lines attached to the canister one of the goes back to the gas tank the other one goes towards the front of the car and at some point someone capped it off with a bolt. Does that line go to anything or is it just a vent line out to the atmosphere. On my mustang the evap canister is nicely tucked inside the front right fender not at the back like most other years did.
