Lemme see--

If the pump draws 8 amps (@ 12 volts), and all of the heat from that winds
up in the fuel (which it basically does , sooner or later), that is 96
watts. Which converts to 327 BTU/hour. which is enough heat to raise the
temperature of 10 gallons of gasoline about 7 degrees over the course of
one hour if none of that heat is dissipated anywhere.

Rough numbers, but close enough to demonstrate why I disagree with your
idea that the pump is the main problem, Tom.
