The Importance of Diesel Fuel Filters: The First Line of Defense for Injectors
High-quality diesel fuel filters are the first line of defense for protecting injectors. This article analyzes the filtration effectiveness of different types of filters.
Filtration Precision
Common rail systems require fuel filtration precision of 2-5 microns, far higher than the 10-20 microns required by traditional mechanical pumps. Using substandard filters can lead to early wear of injectors.
Water Separation
Moisture in diesel fuel can cause injector corrosion and microbial growth. Choosing a filter with water separation function is particularly important.
