Fuel pressure drop when warm...sad day #2

It's also a consequence of normal operation.
What would you recommend? Measuring the temperature of the fuel in your tank when you pull in for gas, and then pre-heating the new gas to match before it goes in the tank? Topping off every 30 miles? Only getting fuel when your car has been driven less than 15 minutes, before the fuel has had a chance to heat up?
And what should people be doing in winter to avoid "fuel pump thermal shock", when the fuel in the the car is 0 degrees, and the gas coming out of an underground storage tank is 50 degrees?

Obviously a return system will add more heat, baring in mind most of the heat will come from the fuel getting heated in the hot fuel rails up front and then getting returned to the tank.
I've tested, and really only a very small amount of heat gets imparted to the fuel from the pump itself.
Although in any case, heating of fuel will always get worse the lesser the fuel capacity you have at any given time.

A lot of "interesting" information in this thread.

I have one and know of a few cars running very small fuel cells that do too.
Pretty much any small oil type cooler will work just fine, stick it on the low pressure return and job done.
