1) What you are describing is expansion of the gasoline in the cars fuel tank, not in the underground tanks.

2) Not sure how this would happen, there is probably some evaporation if the cooled gasoline is introduced into a hot line, but the speed of introduction will have nothing to do with it. Vapor/Liquid equilibrium just doesn't work this way, it's all about temperature and pressure.

But you don't really know where the "Arco" gasoline came from, if you were in LA, then it probably did come from the refinery in Carson, but if you were in Oakland, it probably came from one of the Bay area refineries. You may have gotten it from Arco, but Arco probably arranged for supply with the nearest refinery they could do a deal with.
