318 MAX fuel economy builds?

I was told a long time ago by an chemical engineer (my little league coach) that gasoline doesn’t burn, its the vapors. So when ‘gas’ is heated it gives off vapors, the hotter it gets the more vapors the more fire. Watch when they weld on those huge tanks, it has to be full because gas don’t burn
A little off subject.

I used to work for Progress Industries in Arthur Illinois. We built tanks for trucks and semi trailers. We also did repairs. When it came to repairs we would steam clean the inside of the tanks and then leave the steam hoses in the tank to fill the tank up so there was nothing to blow up.
One day we got in a ink trailer that has that pretty stainless steel outside covering on it and then under that is insulation and then the tank. Well the guy steam clean the tank left the hoses in did not take into consideration the ink that had soaked into the insulation. When he struck an ark it blew him out of the end of the building and blew the end of the building down. He lived. They made him a supervisor.

You might say he got bad gas mileage that day.
