So as we all know, boiling fuel, caused by either heat or decreased vapor pressure at higher altitudes is not a good thing and causes vapor lock. I know that different types of fuel (Avgas VS. Mogas) have different temperatures and vapor pressures at which it boils, but for this discussion let's take that variable out of the equation and pretend that regardless of the type, that it all boils at the same temperature and vapor pressure. So:
1. Does anyone know how much pressure is required to overcome this boiling point and to keep the fuel in its liquid state?
2. As the temperature or altitude increases, does it take additional pressure to keep the fuel in its liquid state? If so, is there a simple formula to calculate that variable?
Thanks,
Mark
