    The water tends to pool at the bottom of the tank due to gravity. Source: former gas station owner. At -40 C the bigger issues are: pump lubrication, metal becoming brittle, shrinkage of parts made of different metals causing friction and wear (but this does tend to heat up the mechanism!), electronics malfunctioning. That's why we had very old pumps without any electronics at all and those functioned very well in deep winter, as long as we had power (for which we had a backup diesel generator). Not a single lost day of business in the four years that we owned that station. Far more modern stations nearby on highway 17 were doing much worse.
