The tips bvelow were sent to me by one of my X students of many years ago. You will find the information to be very cost effective. TIPS ON PUMPING GAS/Diesel or Buying Gas The Smart WayHere in California we are paying up to $3.75 to $4.10 per gallon. My line of work is in petroleum for about 31 years now, so here are some tricks to get more of your money's worth for every gallon:Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening....your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role.A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps. When you're filling up do not squeeze the trigger of the nozzle to a fast mode If you look you will see that the trigger has three (3) stages: low, middle, and high. You should be pumping on low mode, thereby minimizing the vapors that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're getting less worth for your money. One of the most important tips is to fill up when your gas tank is HALF FULL. The reason for this is the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gallon is actually the exact amount. Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up; most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

I got as far as the first suggestion and almost quit reading. Ground temperature really does not change from day to night. Depending on location and depth it may change meaningfully from summer to winter but not in a day.
The other suggestions are worth little more than the first except that it may be good advice to not pump while a load is being delivered. At large truck stops, however, there is always a load being delivered or a delivery was just completed.
Pump your fuel any way you want any time you want. There is no money to be saved from following these suggestions.

Suction lines on fuel storage tanks are on the bottom of the tank. It would little serve station owners to 'leave' a measure of fuel in the tank if the pickup were above the bottom. Various versions of that story have been floating around the web for years.

FWIW.....George
I guess all the citizens of Canada have smoke and mirror advice on the topic of "hot fuel "
Maybe it's just a rumor that fuel is dispensed based on temp. at 67* deg. at the pump giving the customer a true amount.
In a recent U.S.A. lawsuit one fuel stop was estimated at making nearly $ 500M over 40 years selling "hot fuel".

The original message says nothing about heating of fuel. It talks about ground temperature effect on underground storage. You can change the subject but at least say so.
I also don't put much store in one single anecdote about heated fuel. And, how do you protect against that anyway?
What do Canadians have to do with the discussion?
So I'll say once again that the time of day has no impact on the temperature of fuel stored under ground.
