Fleetguard maintenance filter kit for Cummins engines — LF14000NN oil + FF5776 fuel + FS19764 water separator, OEM fit and high-ef

Fleetguard Genuine LF14000NN + FF5776 + FS19764 is a three-piece maintenance filter kit designed to protect Cummins engines by providing oil filtration, secondary fuel filtration, and fuel/water separation in one service set.

This kit bundles three Fleetguard OEM-quality filters matched to Cummins engines: the LF14000NN lube (oil) filter, the FF5776 secondary fuel filter, and the FS19764 fuel/water separator. Together they help preserve engine reliability by removing particulates from oil, capturing contaminants in fuel, and separating water from diesel before it reaches the injection system. Each component is manufactured to Fleetguard standards for fit and filtration efficiency, making this a convenient single-purchase option for scheduled maintenance.

How does this kit protect engine oil and extend oil service life?

The LF14000NN lube filter traps wear particles, soot, and other contaminants that accelerate component wear. By maintaining cleaner oil, it supports consistent lubrication and helps preserve clearances and moving parts.

• High-efficiency filtration media captures fine particulates.
• Reinforced construction resists bypass and collapse under pressure.
• Direct OEM fit simplifies installation and seals reliably.

What role does the FF5776 secondary fuel filter play in fuel system protection?

The FF5776 provides secondary-stage filtration to remove fine solid contaminants and oxidation products that can damage pumps and injectors. It works downstream of a primary filter to provide an extra layer of protection for precision fuel system components.

• Removes microscopic particles that primary filters may miss.
• Helps preserve fuel pump and injector life by reducing wear.
• OEM compatibility ensures proper flow and pressure characteristics.

How does the FS19764 fuel/water separator reduce corrosion and injector issues?

The FS19764 separates and traps free water in diesel fuel before it reaches the engine, lowering the risk of corrosion and microbial growth. Removing water also prevents loss of lubricity and decreases injector wear and fouling.

• Centrifugal and coalescing action helps collect and retain water.
• Reduces downstream corrosion and injector contamination risks.
• Designed for simple replacement and reliable drainage when serviced.

How does choosing this Fleetguard kit simplify maintenance scheduling?

Buying the three matched filters together eliminates guesswork about part compatibility and ensures all critical filtration points are addressed in a single service. That makes routine intervals faster and reduces downtime associated with sourcing individual parts.

• Single SKU covers lube, secondary fuel, and fuel/water separation needs.
• OEM-quality parts minimize fitment and warranty concerns.
• Streamlines inventory for fleets and service shops.

Who is this for: This Fleetguard LF14000NN + FF5776 + FS19764 kit is intended for Cummins engine owners, fleet managers, and independent technicians who want OEM-grade filtration for scheduled maintenance. It suits commercial trucks, industrial applications, and any diesel-powered equipment specified to use these Cummins-compatible Fleetguard parts. Purchase the kit when performing routine oil and fuel system service to restore filtration performance and keep engines running dependably between scheduled intervals.
