Fleetguard FS19915 Fuel Water Separator 6-Pack — Genuine OEM 7-Micron Filter for Detroit Diesel DD13, DD15 & DD16 Engines
The Fleetguard FS19915 6-Pack is a case of six genuine Cummins Filtration EleMax plus-size spin-on fuel/water separator cartridges rated at 7 microns — specifically engineered for Detroit Diesel DD13, DD15, and DD16 engines in 2008-and-newer Freightliner and Western Star trucks. This filter serves as the primary fuel/water separator on the Detroit fuel/coolant module, directly replacing Detroit Diesel OEM part number A0000903651 and Mercedes-Benz A4720921205.
The FS19915 uses advanced StrataPore synthetic multi-layer coalescing media to deliver 7-micron absolute filtration with 95% emulsified water separation, protecting your high-pressure common-rail fuel injection system from both particulate contamination and water damage. The patented control valve ensures full use of the filter media throughout the entire service interval, providing consistent protection even under heavy-duty operating conditions. Fully biodiesel compatible for B5-B20 fuel blends.
Buying a 6-Pack covers a full year of service intervals for a single truck, or one service cycle for a small fleet. The FS19915 fits Fuel Pro and many Diesel Pro housing models. Trusted by fleet managers, owner-operators, and diesel shops across North America for Freightliner Cascadia, Coronado, 122SD, 114SD, and Western Star 4700-6900 series trucks.

These three filters are NOT interchangeable — they have different physical sizes and fit different housings. Always match the filter to your engine and housing configuration.
When to Replace
Replace at each scheduled service interval or when you observe reduced fuel pressure, hard starting, loss of power under load, water-in-fuel warning lights, or fuel system fault codes. The FS19915's 7-micron rating provides fine filtration that captures smaller particles than coarser alternatives, extending injector life on DD-Series engines.
What's Included
6x Fleetguard FS19915 Fuel Water Separator Filters with O-Rings — individually boxed in OEM-sealed packaging. All items are genuine Fleetguard, not aftermarket or repackaged units.
Why Choose Genuine Fleetguard for Detroit Diesel?
Although Fleetguard is the filtration division of Cummins Inc., the FS19915 is specifically engineered and tested for Detroit Diesel DD-Series engines in Daimler Truck (Freightliner/Western Star) applications. The StrataPore coalescing media is calibrated for the Detroit fuel/coolant module's flow characteristics and pressure specifications. Aftermarket alternatives may physically fit but often use media optimized for different flow rates, resulting in either restricted fuel flow or reduced water separation efficiency. On DD13/DD15/DD16 engines where injector replacement costs $8,000-$18,000+, genuine Fleetguard filtration is the most cost-effective protection available.
