TQ question

It occurred to me that Ive never ever thought to look.Its not like one day a guy gets up in the morning and says, "hey I think Ill go pop a vacuum line and see if its wet inside".lol
But then I thought to myself;By the time I shut the engine off, get my fat, lazy *** out to the front, open the hood, remove the air filter house, pop the line and look; Any fuel that was in there should have long ago flashed.
So heres my question; are you sure it was fuel? And how much is a bit? And are you sure it was hooked to the spark port? Some TQs have a purge port up there.The timing of that port is different than the sparkport.
In any case since those ports are on the topside of the Tplates, fuel should not be in there.Those vacuum ports are above the idle discharge ports and mostly above the transfers as well.On a correctly working TQ, I cant imagine how it could get in there. I also cant imagine it being a problem, unless its indicating an internal leak.
