Whunter, I think you would need to also insulate your fuel tank as well or even consider wrapping some sort of heating element around your tank if the sub zero temps you encounter are a big problem. Then, if it would be practical, wrap the full length of your fuel lines from the tank to your engine. Maybe that would work.
