This article from how Stuff Works claims fuel meters are temperature-corrected by the pump computer, but doesn't say anything else about it. I've found some sources online that say temperature correction is required in the EU and Canada. Edit: In the UK and Canada, Automatic Temperature Correction is required at gas pumps. The Wikipedia article on fuel dispensers says,
"There are far fewer retail outlets for gasoline in the United States today than there were in 1980. Larger outlets sell gasoline rapidly, as much as 30,000 US gal (110,000 L) in a single day, even in remote places. Most finished product gasoline is delivered in 8,000- to 16,000-gallon tank trucks, so two deliveries in a 24-hour period is common. The belief is that the gasoline spends so little time in the retail sales system that its temperature at the point of sale does not vary significantly from winter to summer or by region."
With no citation, of course, so who knows?
