I need to make up a vent tube for a YS637 carburator I just installed on my M38. Can anyone tell me the OD of the tubing that I will need to use? I'm refering to the tube that runs from the carb to the crossover pipe. Thanks in advance.

Go to the auto parts store and get the steel brake line. It should work.
