Genuine Fleetguard FS19915 Fuel Water Separator (Pack of 6) | OEM Diesel Filter for Cummins 6.7L

Uncompromising protection for your 2013–2018 Cummins. The high-pressure common rail system in your Ram is only as reliable as the fuel you feed it. The Genuine Fleetguard FS19915 (Pack of 6) is the factory-spec frame-mounted separator designed to stop emulsified water and harmful particulates before they reach your injectors. By choosing Fleetguard—the original equipment manufacturer for Cummins—you are ensuring your truck stays on the road and out of the shop.

🧠 WHY THIS MATTERS

At Valtrix Powertrain, we prioritize engine longevity over all else. The FS19915 utilizes Fleetguard’s proprietary multi-layered media, engineered specifically to handle the high flow rates of the 6.7L Cummins Turbo Diesel. This filter doesn't just "fit"; it is a mission-critical component that prevents tip erosion and pump cavitation. Purchasing this 6-pack allows you to maintain a strict 15,000-mile service interval for the next 90,000 miles, providing consistent, laboratory-grade protection.

❓ FAQ

Q: Is this the same as the Mopar 68197867AB? A: Yes. Fleetguard is the manufacturer for the Mopar-branded version. The FS19915 is the exact same filter element, just in Fleetguard's own packaging.

Q: Do I need a special tool to change this? A: A standard 1-1/8" socket or a filter wrench is usually all you need to remove the frame-mounted filter housing.

Q: How often should I change these filters? A: Cummins and Ram recommend replacement every 15,000 miles under normal conditions. If you are idling for long periods or using high-sulfur/poor-quality fuel, we recommend every 10,000 miles.
