Fleetguard FS19764 Fuel Water Separator 6-Pack OEM Cummins ISX Davco

Fleetguard FS19764 Fuel Water Separator 6-Pack — Genuine OEM for Cummins ISX, Caterpillar C-Series & Davco Fuel Pro Systems

The Fleetguard FS19764 6-Pack is a case of six genuine Cummins Filtration EleMax plus-size fuel/water separator cartridges designed for Davco Fuel Pro 230 and Industrial Pro 234 housings. Buying a 6-Pack covers approximately a full year of service intervals for a single truck or a single service cycle for a small fleet. Each cartridge uses advanced StrataPore synthetic multi-layer coalescing media rated at 10 microns to deliver 98.7% particulate filtration efficiency and 95% water separation — protecting your high-pressure common-rail injectors from both contamination and water damage.

Unlike standard fuel filters, the FS19764 is a dedicated fuel/water separator that actively removes emulsified and free water from diesel fuel. Water in diesel causes injector corrosion, tip erosion, and premature fuel system failure ($5,000-$15,000+ in repairs on ISX engines). The FS19764's patented control valve ensures full use of the filter media, providing maximum contaminant-holding capacity and extended service life. Fully biodiesel compatible for modern fuel blends.

This 6-Pack is the smart choice for fleet managers, owner-operators, and diesel shops who want to stock up, save per-filter, and maintain uninterrupted maintenance schedules across their Freightliner, Kenworth, Peterbilt, International, Western Star, and Volvo trucks.

Note: The FS19764 is a CARTRIDGE filter designed for Davco Fuel Pro 230 and Industrial Pro 234 housings. Confirm your Davco housing model before ordering. Smaller Fuel Pro housings use the FS19727 (standard size). The FS19764 is the plus-size version with extended service capacity.

When to Replace

Replace the FS19764 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 design provides increased contaminant-holding capacity for extended service intervals compared to the standard FS19727.

What's Included

6x Fleetguard FS19764 Fuel Water Separator Cartridges with O-Rings — packed in one factory-sealed Fleetguard box. Each cartridge is individually sealed. You receive a full case of 6 genuine Fleetguard separators, not aftermarket or repackaged units.

Why Choose Genuine Fleetguard?

Fleetguard is the filtration division of Cummins Inc. The FS19764 is engineered, tested, and approved by the same company that builds your ISX engine. 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 that cost $5,000-$15,000+ on Cummins ISX engines. Genuine Fleetguard provides the insurance your fuel system needs.
