Tips on pumping gas

[blindingillusion]

It has about half the specific heat capacity of water, so yes, that first half a gallon to a gallon may be slightly expanded due to heat, but anything after that isn't going to spend enough time in the hose to effect it.

(specific heats in kJ/kg*K )
Water, fresh 4.19
Gasoline 2.22

but anything after that isn't going to spend enough time in the hose to effect it.

See...that makes sense too. I think the gas would be moving so quickly that it wouldn't have an effect on it.

The gas has already been metered by the time it gets to the hose, so even a hot black hose would have no affect on how much gas you get.
