What preventive maintenance is crucial for ensuring fuel quality in a Type 4 system?

Regular strainer cleaning is essential for maintaining fuel quality in a Type 4 system because strainers are designed to filter out impurities and contaminants that can compromise fuel integrity. Over time, particulates, sediment, and other debris can accumulate in the strainer, leading to reduced flow rates and potential clogs. If the strainer is not cleaned regularly, it can allow particulates to pass into the fuel system, which can cause damage to pumps, injectors, and other critical components, ultimately affecting the performance and longevity of the equipment.

Maintaining clean strainers ensures that only high-quality fuel enters the system, minimizing the risk of operational issues and maintaining effective fuel delivery. This practice is a fundamental aspect of preventive maintenance, directly influencing fuel quality and the overall efficiency of the system.
