RE: Custom fuel tanks
I have used 16oz, 20oz, and 32oz Coke bottles as fuel tanks. Throwing them against a brick wall full of water does not break a Coke bottle. Titebond 8oz glue bottles are the same size as Sullivan 8oz oval tanks. I am also getting ready to use a pair of 4oz oval Elmer’s glue bottles. No one makes a 4oz oval tank. A 6oz oval tank is preferred.
Hope the information helps.
