How well do these pumps

How well do these pumps handle heat? Temperatures 20 to 50 degrees hotter than ambient. 90 to 140+ F. Combined with a small tank volume of 19Liters  (5 US Gal)

fuel pump temperatures climb to point of failure. I can't run this machine below a half tank of fuel in summer temperatures. Any suggestions?

Heat sinks for the pump, a better pump to handle the heat? or possibly a fuel/return line cooler.

Any fuel pump will fail if

Any fuel pump will fail if fuel temp is too hot. The problem is that the liquid is boiling in pressure producing chamber or just before entering it.

 

Some pump types and models can handle it few times and some fail immediately, and they all will fail in time. I'd say return line cooler is best solution here.
