What does the term "fuel polishing" refer to?

The term "fuel polishing" refers specifically to the process of filtering and recirculating fuel to remove contaminants. This process is crucial for maintaining the quality of fuel, as contaminants such as particulates, water, and bacteria can affect fuel performance and lead to engine issues. During fuel polishing, the fuel is passed through filtration systems that effectively clean it, ensuring that it meets the necessary standards for safe and efficient use in engines. This practice helps extend the life of fuel systems, prevents damage to engines, and ensures smooth operations by keeping the fuel free from harmful impurities.
