It looks like a float bowl vent to me,too.But he did mention that it had suction on it which sounds wrong.BUT,there is a possibility of vacuum being present on a float vent while the engine is being revved.It would be slight,but you could detect it. I'm going with vents on this one.I know it is a completely different carburetor than my round tops,but the basic layout it the same and those tee fittings are bowl vents on mine.
