I'VE been told condensation of the tank's air moisture will freeze and block the fuel line.
the more full the tank,less air less moisture.

one would assume if the car is warm up the inside of the car's temp is different from the outside.

on extremely cold days,my car window also ices up from condensation on the inside.(when i lived in manitoba).Can the same thing not happen inside the fuel tank?
