A lot of heat and little ventilation
The problem
Fuel lines are often forced to stay in close contact with engine components. In aircraft, where spaces are considerably reduced, this problem is even more pronounced. The contact with the engine components, in addition to causing the degradation of the materials of the fuel lines, heavily affects the temperature of the fuel itself which, in turn, drastically reduces the performance of the engine. In the event of overheating, liquid fuel can rapidly pass into a gaseous state causing the dreaded “vapor lock” effect.
