I have seen racers fill their tanks with cooled fuel and try to keep it cool before racing as you are supposed to get more in when it is cold.
I would imagine a pump will only pump the same amout hot or cold.

Diesel Fuel Delivery - Regulations
The diesel fuel delivery regulations, which have been in place for nearly a century, stipulate that diesel fuel be delivered to the pump at 60 degrees farenheit. At 60 degrees the volume of one gallon of diesel fuel is 231 cubic inches and diesel fuel pumps are metered to deliver a gallon of fuel equal to the 231 cubic inch standard.
Even though truck stops measure out your fuel delivery as if it were stored at 60 degrees, however, no law requires them to adjust the pump to reflect the expansion of hot fuel. In other words, no regulation ensures you get what you pay for.
Diesel Fuel Physics
As we know, diesel fuel expands and contracts depending on temperature. At the 60 degree, 231-cubic-inch, standard a gallon of diesel fuel contains a specific amount of energy. At 90 degrees, however, the same amount of diesel fuel expands to more than 235 cubic inches; but truckers still receive the standard 231 cubic inches at the pump.
You've no doubt surmised that every degree, over and above the 60 degree standard, diminishes the energy contained in a 231-cubic-inch gallon. This results in lower MPG and higher consumer costs.

At the end of filling, hold the hose upside down and shake so you get the very last drop.
See lots of people doing this,you will not get any more out past the nozzle unless you squeeze the trigger again which will start the pump going again.

It only makes a difference if you are filling a commercial jet with thousands of litres.
Commercial jets are fuelled by weight, not volume.

I don't hold the hose but do give it a shake, saves dripping diesel down the side of the car.
