Unfortunately it doesnt sound like they produce the old style fuel tanks any more. You can make a new fuel tank work if you replace your return line with a banjo style fitting. If you have any questions or would like to price out a fuel tank or return line you can give me a call at 866-363-8193 or visit us at kenotractors.com
