Which process follows draining the water separator when a WIF alert is activated?

When a Water in Fuel (WIF) alert is activated, the primary concern is to address the presence of water in the fuel system, which can lead to significant engine performance issues and damage. After draining the water separator, replacing the fuel filters is an important follow-up step.

Fuel filters are critical components that remove contaminants and water from the fuel before it enters the engine. When water is present and has triggered the alert, it is advisable to replace the fuel filters to ensure that any residual water or debris is completely eliminated. This helps in maintaining the integrity of the fuel system and protects the engine from potential harm caused by water contamination.

Performing this step is essential for restoring the proper operation of the engine and preventing future WIF issues. It ensures that the fuel supply remains clean and free from contaminants, which is vital for optimal engine performance and reliability.
