What everybody else has said, and turn off your fridge first. If it's full and cold, you can travel for 4-6 hours with it off (as long as it stays closed).
I'm I missing something? What does this have to do with refueling?
Some people think the pilot light on the fridge will set off fumes in a gas station.
If you have ever seen a starter bench tested it will change your mind. They will throw off more sparks then you will see on the 4th of July.
Gasoline fumes are heaver than air and will flow down and along the ground, not up toward the reefer flame. Aircraft hangers, and probably many other commercial buildings, require all electrical plugs be at least 3 feet above the floor for that reason.

We just pull up to the pump, and refuel - I wouldn't care if we had a 100 footer lol... Keep it simple. Some people worry too much, don't be one of those people! Just try to stay to the outside, and a station that has multiple entrances and exits.
