I just bought this clean '69 AT1 from the original owner. It is not running currently, but should be in a day or so. I have a question maybe someone else who has one or has had one could answer. What is this tube here? The clear-ish one that is open ended. The thicker black tube is the oil line from the oil tank. I can't find anywhere the clear tube should plug into, but i don't want to try to start it until I know what it is, incase it is another oil line or something. Does anyone know what it should attach to?
