Genuine Fleetguard FS19915 Fuel Water Separator (Pack of 6) | OEM Diesel Filter for 2013–2018 Cummins 6.7L
Description
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 that stops emulsified water and harmful particulates before they reach your injectors. Choosing Fleetguard — the original equipment manufacturer for Cummins — keeps your truck on the road and out of the shop.
Technical Significance
Engine longevity above all else. The FS19915 uses Fleetguard's proprietary multi-layered media engineered for the high flow rates of the 6.7L Cummins Turbo Diesel. This filter doesn't just fit — it's a mission-critical component that prevents tip erosion and pump cavitation. The 6-pack lets you hold a strict 15,000-mile interval for the next 90,000 miles with consistent, laboratory-grade protection.
OEM vs. Aftermarket Comparison
| Feature | Genuine Fleetguard FS19915 (This Product) | Generic Aftermarket Filters |

| Particle Holding | High-capacity synthetic layers | Lower-grade paper (clogs faster) |
| Cold Weather | Resists paraffin waxing | Prone to gelling and fuel starvation |
| Fit & Seal | Perfect OEM O-ring seating | Risk of air leaks and vacuum loss |

★★★★★ Cleared my water in fuel light after a bad fill-up
Filled up at a station in rural Texas and got a water-in-fuel warning 30 miles later. Pulled over, drained the bowl, and drove to my destination. Put in a fresh FS19915 the next morning and the light has been off ever since. Authentic Fleetguard — you can tell by the media quality compared to the cheap ones I'd been using before.

★★★★★ Great for 2013-2018 Ram owners who tow
I use my 2016 Ram 3500 to tow equipment trailers weekly. High-load diesel use means I'm more aggressive about fuel filter service. This 6-pack at the OEM Fleetguard standard gives me exactly what I need at a much better price than the dealer. Fit is perfect, instructions aren't needed because it's the same as OEM.

★★★★★ Solid OEM filters, fast delivery
Ordered for my 2015 Ram 2500. Filters arrived fast and in good condition. Genuine Fleetguard with O-rings included. The media quality is clearly better than the budget brand I tried once — never again. Four stars only because I wish the 6-pack was a slight bit cheaper, but the quality justifies the price.
