Root cause failure analysis of a high-pressure diesel fuel line: Evidence of cavitation erosion–induced leakage

Key Points

• Leakage due to cavitation erosion was identified as a major issue in the high-pressure diesel fuel line materials.
• Analysis showed physical damage patterns indicative of cavitation erosion affecting the fuel line performance.
• The investigation employed root cause failure analysis to identify factors contributing to fuel line degradation over time.
• The findings support the need for improved design and maintenance practices to mitigate cavitation-related damage in fuel systems.
