Genuine Fleetguard FF5776 Fuel Filter (Pack of 6) | OEM Secondary Filter for 2010–2012 Cummins 6.7L
Description
The final line of defense for your injectors. Your 2010–2012 Ram 6.7L Cummins relies on absolute fuel purity to deliver its legendary torque and reliability. The Genuine Fleetguard FF5776 (Pack of 6) is the factory-spec engine-mounted filter that traps the microscopic silt responsible for injector tip erosion. Don't settle for generic white-box filters that let contaminants slip past — run the OEM technology Cummins engineered for your high-pressure fuel rail.
Technical Significance
Modern common-rail diesel systems have zero tolerance for debris. The FF5776 is a precision secondary filter that "polishes" fuel after it leaves the primary separator. This 6-pack commits you to 90,000 miles of peak performance, keeping your CP3 pump and injectors lubricated and free from the scoring caused by poor-quality fuel.

★★★★★ My 2011 Ram starts like it did on day one
Got this for my 2011 Ram 2500 with 187k miles. The truck had been getting harder to start in the mornings and my fuel pressure gauge was dipping on long hills. Put in a fresh FF5776 and FS19765 and it fired up on the first crank the next day. Like night and day. These filters matter more than people realize.

★★★★★ Correct filter, good price on the 6-pack
Verified the part number against Mopar's interchange list and it matched up perfectly for my '12 Ram 3500. Filters are authentic Fleetguard — not a rebranded generic. The 6-pack gets me through 90k miles of service which is a great deal. Would've been 5 stars but the listing photos could be clearer.
