Which risk increases when elevated fuel temperature in a modern gasoline direct injection (GDI) system encounters extremely high pressures?

💡 Explanation

Vapor lock risk rises because increased fuel temperatures with higher pressures past the fuel pump cause dissolved fuel components to vaporize suddenly via cavitation, leading to lean misfires; therefore, vapor lock is the main concern, rather than increased combustion efficiency.
