When should testing for free water in fuel tanks occur?

Testing for free water in fuel tanks should occur prior to receiving fuel, after 24 hours, and on a monthly basis because this protocol ensures fuel integrity and safety. Water in fuel can lead to a variety of problems, including fuel contamination, engine performance issues, and corrosion of fuel system components.

Conducting tests prior to receiving fuel helps verify that the incoming fuel is free of water, which is crucial for maintaining a clean fuel system from the start. The 24-hour check allows for any water that may have settled in the tanks to be identified shortly after fuel is received. Monthly testing adds a layer of ongoing maintenance to monitor the fuel quality over time, identifying potential issues before they can affect operations. Regular testing is key to preventing costly repairs and ensuring reliable performance.
