Subject: [s-cars] fuel vapor on warm days . . .

There is a tube that runs under the passenger side of the car that vents
fuel vapor on warm days . . . after a good hard run home from work my garage
fills up with fuel vapor from the under side of the car.  Does this happen
to anyone else . . . this really started happening a lot last summer and
starting to notice it again . . . not really noticeable at all this last
winter.  I am running Hoppen/Lehman stage IV software (26-27 max overboost),
8.5:1 compression pistons, RS2 turbo, RS2 extrude honed ex. manifold, RS2
injectors, Lehman modified cyl. head, Strommung 3" turbo back exhaust (mit
cat), stock MAF, metal bypass valve.  I had the dealers recall done on the
fuel line so that is definitely not where the vapor is coming from.  In fact
I can get under the car and see the fumes coming out of the tube I decribed
on a hot day.   Is the just something normal . . . I just can't believe how
vaporous the garage smells and even my wife can tell it aint coming from my
backside.   TIA.
