How often should fuel be recirculated when idle?

Recirculating fuel while it is idle is crucial for maintaining fuel quality and preventing issues such as separation and contamination. Fuel can degrade over time due to factors like microbial growth and sedimentation, particularly when sitting still. To mitigate these risks, it is recommended to recirculate the fuel every 24 hours.

This timeframe strikes a balance between minimizing potential degradation and the practicality of operations. Frequent recirculation helps ensure that any particulates or contaminants are kept in suspension, making it easier to filter them out during subsequent usage. Therefore, maintaining a 24-hour recirculation schedule is essential for extending the life of the fuel and safeguarding the systems that rely on it.
