What is a common sign of a potential fuel leak in a tank?

A common sign of a potential fuel leak in a tank is unexplained drops in fuel levels. This occurs when a tank shows a decrease in fuel volume that cannot be accounted for by normal consumption or usage patterns. If the fuel level is dropping significantly without a corresponding increase in usage or any other logical explanation, it often indicates that fuel is escaping from the tank, which could point to a leak in the tank or a related component of the fuel system.

Regular fuel usage can fluctuate based on consumption needs, and an increase in tank pressure could relate to temperature changes or other factors not directly related to a leak. A higher than normal temperature may indicate other operational issues but does not directly indicate a fuel leak. The key indicator here is a substantial, unexplained drop in fuel levels, emphasizing the need for inspection and possible repair to prevent further loss and potentially hazardous situations.
