Another good-to-know physical attribute of a liquid fuel is its autoignition point. Avgas will spontaneously burst into flames at a temperature of 450 deg.
The theory states that if piping contains a flammable gas and there is an inrush of fluid (or fluid transient) into the piping, the gas can adiabatically compress to its autoignition point (similar to a diesel engine), and then the gas, given sufficient quantity and pressure, can ignite and explode.
