Just asked husband if true about gasoline expansion, etc.
He said yes, but per federal laws and guidelines all tanks are buried at the deep level of 56 degrees and the gas leaving tank going through meter tank, hoses, etc. were calibrated to give you a gallon of gas per gallon. Any lack thereof were too minute to worry about.

He said a jet aircraft (retired from airline) could be sitting on the tarmac, you could fill to full with fuel and after a length of time in hot temp., jet fuel would start pouring out.

A LOT of information here on how gas is measured, dispensed and accuracies. Very interesting.

It's for Arizona, but the discussion is relevant to other states as well.
