I got a 2004 legacy 35th anniversary edition and experienced some evap issues so as I went to replace the vent valve solenoid which i was told would be right next to the charcoal canister is not there same goes for the purge valve thats suppose to sit behind the intake manifold. Any insight on where these parts may be located would be appreciated this is my first subaru.

I have noticed that my legacy struggles to turn over after fueling up, it takes a few key turns and a couple presses of the gas peddle to get things running. My first thoughts would be injector, fuel filter, or evap line. This has happend filling just a little bit and also filling its near limit.
