Fleetguard Cummins maintenance filter kit LF14000NN + FF5776 + FS19764 — lube, fuel & water-separator

This genuine Fleetguard maintenance filter kit contains LF14000NN, FF5776 and FS19764—lube, secondary fuel and fuel water-separator filters engineered to protect Cummins engines during routine service.

When servicing a Cummins-powered vehicle or machine, using matched OEM filters helps maintain fuel and lubricant cleanliness, reduce wear, and support predictable maintenance intervals. This kit bundles the Fleetguard LF14000NN lube filter with the FF5776 fuel secondary filter and FS19764 fuel water separator so you have the core filtration components needed for a standard service stop. Each part is manufactured to Fleetguard quality specifications and intended to meet or exceed original equipment performance for filtration efficiency and durability.

What does each filter in this kit do for my Cummins engine?

The three filters serve distinct roles: the LF14000NN traps contaminants in the engine oil, the FF5776 removes particulates from fuel before the injection system, and the FS19764 separates and removes water from diesel fuel. Together they reduce wear, protect injectors and pumps, and help prevent corrosion and fuel-system damage.

• LF14000NN: engine oil filtration against metal particles and soot.
• FF5776: secondary fuel filtration to capture fine particulates.
• FS19764: fuel water separation to protect pumps and injectors.

How will swapping to this Fleetguard kit affect maintenance intervals?

Using correct OEM-spec filters supports designed service intervals by maintaining system cleanliness and reducing accelerated wear. Replace filters according to Cummins recommended schedules or earlier if operating in heavy-dust, high-moisture, or poor-fuel-quality environments to retain performance and reliability.

• Follow Cummins service manual for replacement mileage or hours.
• Monitor engine oil condition and fuel-water sensor alerts.
• Consider earlier change intervals in extreme operating conditions.

Are these Fleetguard parts compatible with my Cummins model?

The LF14000NN, FF5776 and FS19764 are specified for a range of Cummins engines and applications; compatibility depends on engine model and installation configuration. Check your equipment parts manual or provide your engine serial/model number to confirm fitment before purchase.

• Verify part numbers against your Cummins parts list.
• Contact your dealer with engine serial for cross-reference help.
• Single-kit purchase simplifies ordering the three common service filters.

How should I install and dispose of these filters?

Install filters following Cummins or Fleetguard installation guidelines: clean mounting surfaces, hand-tighten per torque specs, and prime if required. Used filters and drained fluids are regulated waste—dispose of them in accordance with local environmental regulations or via an authorized recycler.

• Use proper sealing gaskets and torque values during installation.
• Prime fuel filters if your system requires bleeding to avoid air locks.
• Collect and recycle used oil, fuel and filter elements responsibly.

Who is this kit best for? Technicians, fleet managers and owners who service Cummins engines will find this Fleetguard kit valuable for scheduled maintenance or mid-life service work. It is ideal for on-site mobile service trucks, fleet spare-part stocking, or DIY owners who prefer OEM-fit filtration to maintain engine performance and reduce downtime risks. If you need parts that match factory specifications for lubrication, fuel cleanliness and water separation, this three-piece Fleetguard kit provides a straightforward, single-order solution.
