Genuine Fleetguard FS19764 Fuel Water Separator | OEM Spin-On Filter for Cummins & Caterpillar Engines
Description
Don't let water contamination grind your heavy-duty engine to a halt. Moisture is the number-one enemy of any diesel fuel system, and the Genuine Fleetguard FS19764 is the industrial-grade spin-on separator built to stop it. Engineered with proprietary Stratapore™ media for the extreme demands of Cummins and Caterpillar platforms, it strips microscopic water droplets and contaminants that corrode and destroy high-pressure injectors.
Technical Significance
Industrial uptime is everything. The FS19764 isn't just a filter — it's a precision barrier. Unlike standard "will-fit" filters that let emulsified water slip through, Fleetguard's multi-layered Stratapore™ technology captures the fine water and debris that cause injector tip erosion. Running this OEM-spec separator keeps your engine at peak fuel economy and inside factory operating tolerances, even in the harshest environments.

★★★★★ Saved my Cat C9 from a bad batch of fuel
Pulled a water-in-fuel alarm on my excavator after a sketchy fill-up at a rural station. Drained the bowl, slapped in this FS19764, and ran a purge cycle. Machine fired right back up and ran smooth all day. The Stratapore media is no joke — you can actually see the junk it catches when you drain it. Will always keep a spare on the shelf.

★★★★★ Genuine Fleetguard, no issues
I manage a small fleet of Cummins-powered trucks and I will not use anything but genuine Fleetguard on the fuel system. This one fit perfectly on our QSB 6.7 engines. Threads went on clean, torqued to spec, zero leaks. Exactly what you'd expect from the OEM brand.
