We would use these when I used to run car's at the drag strip. Maroso makes on that is well insulated. You could put Ice in in the morning and it would be there all day. It should work (very close to what ford is doing on the lightning with the A/C) but thought I would ask if anyone has done this. Any way you can cool the fuel should help right. I would not be good for daily drivers but should be good for crusin around on the weekends>
