=> original location.) it's black, about 3/8" outside diameter, 17.5" length
=> (~44.45cm) and it has small brass disk fitting to slip fit onto something on
=> one end only. the other end has some stuff looking like road crud making me
=> think this may be cousin to one of the other black tubes in this
=> neighborhood snaking up to disappear under gas tank. i'm thinking maybe
=> breather vent tube because the other end has no appearance of ever being
=> crimped to anything and there are no plumbing fittings. brass disk end
=> looks like a real low tolerance item in that there are no threads, slip fit,
Hmmm...is it the drain tube for the overflow "tray" around the gas filler cap?
I know that tube:
vents to the air (and would have road crud at one end)
has a slip-fitting at the other end
Try taking all the Q&%(#)! plastic off from the top of the tank and see if the
overflow tube is gone.
