[OLD SKL 69]

I agree with you. My assembly manual does not show any charcoal cannister or what to do with these extra lines. I figured someone might have a 68-72 cutlass or know of one, and what their car looked like. For all I know, this tank could be from another car. I was thinking of capping one of them, and putting some kind of a filter on the other. All I know is, these lines are pretty close to the exhaust system and I can't imagine it left the factory this way.
