From back in the 60's sometime. All tanks had to feed from the top for "safety" considerations. Even older truck fuel tanks had to be converted from bottom supply to top, local DOT would impound your truck if caught on the highway with "old style" tanks.

Check around the sending unit and see if there is another opening about the same size...

Thanks....I was also thinking this thouhht carb'd engines don't need a return line where fuel injected do....and yes there is another circular flat spot on top of tank but needs cut out. Or should I find a compatable sending unit that incorporates the pickup line which the new original didn't have. I emptied the tank and using a 5gallon jug as temp tank for now.
