What is a critical aspect to monitor during fuel handling?

Monitoring pressure levels during fuel handling is crucial for ensuring the safe transfer and storage of fuel. Fuel systems are designed to operate within specific pressure ranges, and both overpressure and underpressure can lead to serious issues, including the risk of leaks, fuel spills, or even system failures. Maintaining proper pressure helps to prevent vapor lock and ensures that fuel flows efficiently through the system.

While fuel color, temperature, and fluid clarity are important factors in their own right, they are secondary considerations when compared to pressure levels. Color can indicate contamination or degradation, temperature affects fuel density and volatility, and clarity provides insight into the presence of particulates or water in the fuel. However, without monitoring pressure, the risk of catastrophic failure increases significantly during fuel handling operations.
