Fleetguard® FS19915 Plus Size EleMax™ Fuel / Water Separator for Detroit DD13, DD15 & DD16 Engines

The Fleetguard® FS19915 Plus Size EleMax™ Fuel / Water Separator is a premium heavy-duty cartridge filter engineered to protect Detroit Diesel DD13, DD15, and DD16 fuel systems from water, dirt, rust, and abrasive contaminants. Designed with Fleetguard's advanced StrataPore® filtration media and patented EleMax™ technology, the FS19915 delivers exceptional fuel cleanliness while maintaining excellent fuel flow under demanding operating conditions.

Modern common rail fuel systems operate at extremely high injection pressures, making fuel cleanliness more important than ever. The Fleetguard FS19915 effectively separates water and captures fine contaminants before they reach expensive injectors and high-pressure fuel pumps, helping reduce wear, prevent corrosion, and extend fuel system life.

The Plus Size EleMax™ design offers increased contaminant-holding capacity and longer service life while maintaining OEM performance. It is a trusted choice for commercial fleets, owner-operators, and diesel repair facilities looking for premium fuel system protection.

Why Water Separation Is Essential

Water contamination is one of the leading causes of injector failure in modern diesel engines. Even small amounts of water can reduce injector life, damage precision fuel system components, and contribute to corrosion inside the fuel system.

The Fleetguard FS19915 Plus Size EleMax™ uses advanced StrataPore® media and a patented control valve to maximize filter utilization while efficiently removing water and contaminants. This helps maintain proper fuel system performance, improve reliability, and reduce long-term maintenance costs.
