Vapor lock:
When the fuel line is installed in a warm location, e.g., right next to a hot part of the engine, vapor lock can occur in the line. This means that due to the heat of the line, a gasoline vapor bubble can form. This will partially or completely interrupt the fuel supply.
To prevent this, the fuel line should always be installed at some distance from hot engine parts and be as well insulated as possible. Maintaining sufficient pressure in the system also prevents this. In a liquid system under pressure, the liquid will not boil at 100 degrees Celsius. Consider the car’s cooling system. The coolant can also reach 120 degrees when under pressure without boiling. The coolant will only boil when the system pressure is released.
