Fleetguard FS19765 Fuel Water Separator 6-Pack — Genuine OEM for Cummins ISX, Volvo D11/D13/D16, Mack MP7/MP8 & PACCAR MX Diesel Engines
The Fleetguard FS19765 6-Pack is a case of six genuine Cummins Filtration EleMax plus-size fuel/water separator cartridges rated at 25 microns. Engineered for Davco Fuel Pro 230 (FH230) and Industrial Pro 234 (FH234) housings, this filter provides 98.7% particulate filtration efficiency and 95% water separation — protecting your high-pressure common-rail injectors from both contamination and water damage.
Unlike the FS19764 (10 micron), the FS19765 operates at 25 microns, making it the correct choice for 1998-2002 Cummins ISX applications and the factory-standard fuel water separator for Volvo and Mack trucks. The FS19765 directly replaces Volvo OEM part numbers 85120233, 21737499, and 21737481, as well as PACCAR 382951PAC25 for Kenworth and Peterbilt trucks with PACCAR MX engines.
Buying a 6-Pack means you have a full year of service intervals covered for a single truck, or one service cycle for a small fleet. Each cartridge uses advanced StrataPore synthetic multi-layer coalescing media to actively remove emulsified and free water from diesel fuel. Trusted by fleet managers, owner-operators, and diesel shops across North America for Freightliner, Kenworth, Peterbilt, Volvo, Mack, and International trucks.

Important: The FS19765 is a CARTRIDGE filter for Davco 102528 housings. It is the 25-micron version. If your Davco housing uses 102527, you need the FS19764 (10 micron) instead. Confirm your Davco housing part number before ordering.

Both are EleMax plus-size cartridges with the same physical dimensions (178.79 mm height, 106.93 mm OD). They are physically interchangeable but have different micron ratings. Always match the filter to your Davco housing number.
When to Replace
Replace at each scheduled service interval or when you observe reduced fuel pressure, extended cranking on start-up, loss of power under load, or fuel-restriction fault codes. The plus-size EleMax design provides increased contaminant-holding capacity for extended service intervals compared to the standard FS19728.
What's Included
6x Fleetguard FS19765 Fuel Water Separator Cartridges with O-Rings — packed in one factory-sealed Fleetguard box. Each cartridge is individually sealed. All items are genuine Fleetguard, not aftermarket or repackaged units.
Why Choose Genuine Fleetguard?
Fleetguard is the filtration division of Cummins Inc. The FS19765 is engineered, tested, and approved by the same company that builds the ISX engine and supplies OEM filtration to Volvo and Mack. Aftermarket water separators may physically fit your Davco housing but often use inferior coalescing media that allows water to pass through to your injectors. Water in diesel fuel causes injector tip erosion, nozzle corrosion, and catastrophic fuel system failure — repairs costing $5,000-$15,000+ on heavy-duty diesel engines. Genuine Fleetguard provides the insurance your fuel system needs.
