I've got a new smell question.

Every time I fill my gas tank, the inside of my van smells horribly of
gasoline for about ten minutes, till it airs out.  I'm not spilling
gasoline, I'm not getting it on my hands or my car keys or anyplace else.
It doesn't matter whether I leave the van doors open or closed while I'm
pumping.  The gas station doesn't reek of gasoline - though I have noticed
that in this part of the world they don't have those things on the pumps
that prevent fumes from going into the air.

Suggestions?  Explanations?
