I danced around with this problem and now have gone with a tank without any sign of ever leaking. Late '31 Frod ditched the column supported by the tank for very good reason. Another congenetal defect like the flywheel and its housing was not fixed until the Model B. One fix that should survive on '30 or early '31 cars is to remove the upper clamp on the tank completely and patch it in a safe manner. A late '31 column support replaces the bracket. Not at all a quick fix but solid. Good Luck: Fred A
