gas tank

I am not 100% sure, but I think the 1971 and 1972 Seafari tanks were the same. If so, my diagram with dimensions should help you - it is a 32 gallon tank in the 1972, so yours should hold about the same. The attached diagram was initially prepared by Bushwacker, who also had a '72. The tank should slide back towards the stern, then tip out and up.
