Just tried to get my car smogged and was told that it failed the Evap test because of a bad filler neck. Anyone now if this is a one piece or 2 piece fix? They told me they would use a universal filler neck. But i'm wondering if it is welded to the tank. Would it be better to find a replacement tank with filler neck? Or is that even possible? Bummed it failed the test. It hadn't failed a test yet since i got the car over 10yrs ago. More bummed because it seems like its a pain to fix or expensive to have someone fix it.
