Which outcome occurs when dissolved water contaminates gasoline?

💡 Explanation

Vapor lock occurs because water contamination lowers gasoline's vapor pressure, leading to premature vaporization in the fuel pump's low-pressure zone; therefore, vapor bubbles impede fuel delivery, rather than improving combustion or catalytic converter performance.
