John, I know you mean well, but...
Fuel stored in underground tanks is at a more or less constant
temperature.
Pumping fuel more slowly lengthens the time your tank is open to
atmosphere negating any supposed benefit, and the difference is nil.
Best advice I heard to-date: a) drive like you have an egg under your
right foot and b) preserve momentum.
Chris.
