I remember seeing a gas station security video of this, pre-YouTube. A woman wearing what looked like a fuzzy (static-y) sweater accidentally sparked the gas at the filler door, igniting the gas in the line. She had the presence of mind to close the filler cap before running from the car, which probably starved the fire sufficiently to prevent anything more interesting from showing up on the video. That said, I'm not entirely certain that a fuel filler fire would overtake the entire car. It may just burn out the remaining fuel via the fuel door, so long as the components of the fuel system are sufficiently fire-retardant (no guarantee). When new Ferraris burn themselves down in seconds (happens a lot), I believe it tends to be because something has allowed the fuel pump to continue operating after the line has ruptured, and so the pump is pushing a constant stream on high-pressure flammable liquid onto a hot engine. As long as there's still electricity, the fire will get bigger and bigger.
