Fuel Water Separator (Primary Fuel Filter) - Standard Efficiency

• Removes more than 98% of debris 10 microns and larger - and eliminates virtually all free water and more than 87% emulsified water.
• Minimize the risk of plunger-to-barrel scuffing and seizure in fuel injectors, reducing failure rates.
• Extends the life of engine fuel injectors and the secondary, high efficiency fuel filter.
