Questions: My 1951 M38, apparently, had its tank replaced with a CJ tank (smaller filler neck) at some time in its life. Is it possible to obtain just the 4" fill neck to have a shop weld that in place and properly adapt this tank to my military-spec vehicle? Would your tank supplier be willing to sell that important part separately through you?

Sorry, you cant get just a spout for it. You would have to fabricate that locally.
