Aluminum tanks weigh the same as the old steel Tern-Plate tanks

Just as winter was starting the new Aluminum fuel tanks finally were installed. With the interior baffles they weigh the same as the old steel tern-plate tanks. I was somewhat surprised. That shows how the old 1940s solder coated tern-plate tanks were actually a real innovation at the time. Too bad the creases inside trapped water and made rust spots over 70 years. My old ones were marked 1947.

Hope for the best. Apparently there are different qualities of aluminum tanks. In the early 2000s we had a rash of failures in Decathlons. My 1977 aluminum tanks are apparently still good as new.

I know of no J3s with terne plate tanks still installed. Wish I could buy an aluminum tank for the J4.
