[Healeys] Fuel bill up in filler pipe

[Len and/or Marge Hartnett]

Dan:  Trust me.  If I fill up my tank to the point that I can see the 
gasoline in the filler neck, and this is a few inches down from the top, and 
I drive the four blocks to my house and park in my driveway on a 100 plus 
degree day, the gasoline will expand and overflow the tank.  It is not the 
vapors that cause the problem, it is the gasoline expanding from its 
temperature underground to the ambient air temperature above ground.
