this dosen't happen at any specific time or for any reason, but when i fill up the gas tank a good majorty of the time it will only fill up to 15 gallons, not the "full tank" 
don't pump to fast you can create gas bubbles then the pump will shut off to soon and get gas at night when the temp is down cause gas is sold by volume not weight
But ground temp has an average temp and stays at that temp. Especially with thousands of gallons cooling each other. It doesn't have time to warm up before it reaches your tank.
