The motor will get very hot.! Gasoline has a flash point of -45°F and an auto-ignition temperature of 536°F.Dec 11, 2014
The motor would be a lump of molten metal long before the pump got that hot.
All these years, and I thought gasoline was potentially dangerous. And now I find out that it’s not. Good to know.
Gasoline is dangerous when it is in a gaseous state or near oxygen. The motor shown is non thermostat temperature controlled and will always run colder than a motor with a 143° F thermostat in it. The fuel is totally enclosed with no air contact. The pump itself is also self cooling with the flow of fuel thru it so heat transfer shouldn’t be an issue. No problems!
