Genuine Fleetguard FS19765 Fuel Water Separator (Pack of 6) | OEM Diesel Filter for 2010–2012 Cummins 6.7L
Description
Stop water contamination before it stops your Cummins. For 2010–2012 Ram 6.7L owners and fleet managers, fuel purity is the difference between a productive day and a costly breakdown. The Genuine Fleetguard FS19765 (Pack of 6) is the factory-spec fuel water separator engineered to remove 95% of free and emulsified water. This bulk 6-pack gives your engine the exact protection Cummins intended — service after service.
Technical Significance
The 6.7L Cummins relies on its fuel to lubricate the high-pressure pump and injectors. Even microscopic water droplets cause pitting and corrosion that lead to total system failure. The FS19765 uses Fleetguard's proprietary Stratapore™ media, a multi-layered synthetic with far greater particle-holding capacity than standard paper. This pack keeps you on a strict maintenance schedule for the next 90,000 miles, shielding your powertrain from the inconsistencies of pump fuel.

| Seal Precision | OEM-grade nitrile O-rings | Risk of fuel leaks and air intrusion |

★★★★★ Winter prep done right
I always change both fuel filters before winter here in Minnesota. Got this FS19765 6-pack and the FF5776 6-pack together for my 2012 Ram 4500. Zero issues starting in -20°F weather all season. The Stratapore media holds up in cold fuel way better than cheap paper. Water-in-fuel light has stayed off all winter.

★★★★★ Fleet staple for our 2010-2012 Ram trucks
We have 4 trucks in this model year range and this 6-pack keeps us stocked for over a year. Genuine Fleetguard with OEM O-rings. They thread on smooth and seal perfectly. Never had a leak or a water-in-fuel code while running these. Exactly what we need.
