Try again - 200q problem

[Brian Armstead <barmstea@ibb.gov>]

Listers:  I have a strange problem with my '89 200q (early model).  When
it's cold out side, everything runs fine.  Let it warm up past 70
degrees, and I get very strong gas fumes emanating from the area around
the fuel distributor.  It is NOT the distributor itself, my sniffer
confirms that.  Could it be a bum carbon canister filter/valve?  Temp
was in the 70s two days last week here in Maryland, and it got pretty
bad.  Turned on the econ fan to cool the interior, and the fumes came in
the cabin.  No symptoms I can point to that would cause this.  Car
passed Maryland's treadmill emissions test yesterday with flying
colors.

Help!!
