hi. i have a 2003 sub forester n/a. i cant put gas in it since the filler pipe has been replaced ( valve on filler pipe also changed). rechecked hoses ok, nothing blocking filler pîpe. switched purge valve (near intake), same trouble. canister valve jammed. replaced valve. now can put gas but after a while ( when pressure builds up i guess), cant put gas in it. code cel i get are : p0457 evap big leak and p0453 pressure sensor ( on tank i think). any ideas... thanks.

If these problems started after the filler neck replacement. I would check all of the hoses to the neck and the charcoal canister. The tank has to vent during the fueling process. I would think that maybe a hose has a kink in it it does not make sense that something else would fail after this repair
