Which risk increases in a fuel injection system when fuel temperature exceeds its Reid Vapor Pressure (RVP) specification?

💡 Explanation

When fuel temperature exceeds RVP, vapor lock and cavitation can occur in the fuel lines and pump because the fuel vaporizes, reducing the pump's efficiency and potentially causing it to stall the engine. Therefore, pump cavitation results, rather than coking, line bursts, or poisoning, which arises from different fuel properties or systems failure modes.
