CAT WATER SEPERATOR

This is a primary fuel water separator filter for Caterpillar diesel engines. It is designed to remove virtually all free water and up to 90% of emulsified water from diesel fuel, helping protect high-pressure fuel injectors and extend the life of secondary fuel filters. Regular replacement is critical when the filter becomes clogged or when you notice water accumulation in the separator bowl, as untreated water can cause injector erosion and fuel system damage. This spin-on style filter is used on Cat engines such as C-10, C-12, C13, C15, and C16 in trucks and industrial equipment.
