Wind chill only applies to bodies that are heated not fuel tanks that are at ambient temperature conditions. Wind chill would apply to a fuel tank in a 72 °F garage overnight and then exposed to a lower temperature with the wind blowing. But once the fuel tank and fuel cools to the ambient temperature, it does not get colder than the ambient temperature. That is it would cool faster than without a wind but would not get any colder than the ambient temperture.
The wind chilll numbers that you hear in weather reports are for human skin at 98.6°F and are based on heat transfer rates. The wind chill temperature is the temperature that skin would have to be exposed to with no wind velociy over it to have the same heat transfer rate, BTU's/sec/sq ft as would occur with skin at 98.6°F exposed to a higher ambient temperature with wind passing over it at a given velocity.
