FS19765 FuelSeparator Cartridge

Product Description

FS19765 is a 25-micron primary fuel/water separator cartridge designed for heavy-duty diesel fuel systems used on Volvo and Mack engines.

Featuring** **the FS19765 is engineered to provide effective separation of both free water and emulsified water, while helping remove particulate contaminants from diesel fuel before the fuel reaches sensitive engine components.

As a primary-stage fuel/water separator, the FS19765 is designed to support reliable fuel-system operation, protect downstream fuel filters and injection components, and help reduce the damaging effects of water and contaminants in diesel fuel.

Filtration & Water Separation

The StrataPore® coalescing media is designed to combine particulate filtration with water-separation performance. During operation, water droplets can be coalesced and separated from the fuel, helping prevent water from continuing downstream toward the fuel injection system.

Effective fuel/water separation is particularly important in heavy-duty diesel engines because water contamination can contribute to corrosion, fuel-system wear, poor combustion, and component damage.

The FS19765 therefore serves as an important primary-stage protection element in compatible Volvo and Mack fuel systems.

Installation & Maintenance

For best results, replace the FS19765 according to the equipment manufacturer's recommended maintenance interval or whenever fuel-system conditions indicate that replacement is necessary.

Before installation:

• Confirm the FS19765 part number.

• Verify engine model and serial number.

• Check the fuel-filter housing configuration.

• Confirm the required primary and secondary filter arrangement.

• Inspect seals and the filter housing before installation.

• Follow the engine manufacturer's fuel-system service procedures.

Important Fitment Note

The FS19765 is a 25-micron primary fuel/water separator element. It should be used with the appropriate secondary fuel filter where required by the engine/fuel-system configuration.

Always verify the engine serial number, fuel-filter housing, and current OEM application information before ordering or installing a replacement filter.
