While the physics of it are true the tanks are buried deep enough that the temperature is essentially constant. Besides if this were the case then you would want to wait and use a pump somebody else just used as they would have pumped all the "hot" fuel from the lines that are above ground and then you would be getting all the "cold" fuel.

From the Kinder Morgan web site the San Jose Terminal has a 996,800 barrel storage capacity. If you use a US liquid gallon barrel (31.5 gal) That makes 31,399,200 gallons. If you use a petroleum barrel (42 gal) that makes 41,865,600 gallons storage capacity in 32 tanks. Slightly more than the 16.8 million gallon capacity advertised 34 tanks.

I always understood the reason for the internal floating roof on the storage tanks was to prevent to buildup of vapors, not to prevent evaporation. Both are bad in the grander scheme of things.

There are just too many things which don't add up so I am throwing the bull honkey flag.
