However.....it can be tough to tell if you really smelled fuel at that point or not.
It WOULD explain a lot if it is leaking....but this would be the first time that I have seen it mentioned (not that it cannot or does not happen).

Well what I did was pull the vac line from the intake manifold and put it directly under my nose while the engine was running while I was plugging the intake manifold with my finger. I smelled it only once and it was definitely gasoline smell, but it was faint and only there for maybe 1-2 seconds. Also, engine wasn't at full temp yet either.

I was just thinking about it though - there's a diagram of the fpr in the cd-rom I have and its very clear that fuel and vac are supposed to be separate so I shouldn't have even smelled a hint of fuel however I really don't see how thats possible that the seal would be 100%. It seems like as the diaphragm slides up and down you would smell "some" small margin of fuel here, but so far no one else has said that and I'm probably looking too far into this. Its probably just bad and may have gone bad when the engine overheated above the "H" mark in October. So it would be rare in NORMAL situations for it to go bad, but in an abnormal situation where the engine got that hot it may have melted the rubber internals (assuming the diaphragm is rubber).
