How are fuel leaks typically classified?

Fuel leaks are typically classified into categories based on the characteristics of the leaks, particularly by their visibility and the degree to which fuel is escaping. This method of classification includes descriptors such as stain, seep, heavy seep, and running leak.

This classification system helps technicians quickly assess the seriousness of the leak. A stain represents the smallest category, often indicating minimal leakage, while a running leak suggests a significant and immediate concern that may require urgent attention. By using this system, maintenance personnel can prioritize repairs based on the severity of the leak and ensure safety protocols are followed. Such an approach provides clarity and consistency in diagnosing fuel system issues, making it easier to implement corrective measures effectively.
