I don't know about a.m. fueling. If the fuel is coming from a 1000+gallon tank below ground, how much can the ambient temperature heat it?
Maybe heats the pumping components, but as soon as the cooler fuel runs thru it, it will cool down as well.
I do agree with comments about automobile gas tanks or fuel cells. The fuel will expand and contract. This is why you should keep a full gas tank during seasons where there are big swings in temperature. This causes condensation. and the more available inside gas tank surface, the more water is introduced in your gas.
