I've built one gas tank and I got the filler neck, cap and threaded outlet where the petcock goes by cutting them out of an old peanut tank. I'd like to build another one, but I don't want to cut up another perfectly good (though ugly) peanut tank. I need the filler neck and outlet fitting to be steel but searching for these things on google has caused my bald spot to double in size. Does anyone have a good source for at least a steel filler neck?
