..... ? A small backup generator is all that's required for the gas pumps to work. The state of Florida now mandates gas stations have back up power on evacuation routes, a law enacted from lessons learned from all of the problems caused by Hurricanes Wilma and Katrina. The state of Louisiana I believe also has a similar requirement but I haven't checked.
