I have a 2004 Subaru forester and have been having the same issue trying to fuel up and the tank not venting properly. I have fixed it once for a short time and just fixed it again the same way by removing the solenoid valve located just to the right of the evap canister behind the right rear wheel. When attempting to blow through this valve it was not letting much air in. Gave it a tap and that freed up the valve. I put everything back in shot to the gas station and filled it up like a dream. Took it back today to show the wife what a good provider I was and what would you know it did not work again. When I pulled the valve off it was stuck again. A little rap and it was free. I think the control system usually keeps this vent on low flow and when you are filling it is supposed to open up to allow venting of gases through the canister. I also think it is in line before the canister so removing the lines at the canister did not help you. (I tried that 1st as well.) If it is in the same location as mine you should see a larger diamer 'S' shaped hose coming off of the canister and going up to a valve with an electrical connection (this is the one you want to check). On the other side of the valve the hose goes up to a vent filter which is just a large open can (I expect to keep liquid and debris from clogging the lines as there did not appear to be any filter material inside. the hose after the filter then returns to the tank. I think if you wanted to do a quick check you could pull the hoses off at the solenoid valve and try filling then. To keep this from reoccuring I will be heading off to see how much a replacement valve is going to cost me. I am guessing I will still be saving money avoiding the diagnostic charges and install work from the dealer.
