    Id guess if the purge was sucking fuel from the tank it could run rough but i doubt fuel would make it past the canister. Un plug the purge and see if the problem persists.

    If you un plug it (electric part) and you still feel vacum on the fuel tank side then the purge is bad and unplugging it will not help.

    Well same thing happened to my brothers VW Jetta his but in his case car would run perfectly until it came to fill up the tank. Every time he would fill up or the car would stay out in a really sunny day the car wouldn't start right away, also like 5 to 10 min to get it to start.

    Turns out it was the canister purge valve (N80) in his case, that was stuck open all the time and when it came to fill up the tank the fumes from the tank would flood the engine , or so we where told, took it off and cleaned the valve with carb. cleaner, works great for now while he picks up a new one.
