Complete Oil and Fuel Filtration Maintenance in One Convenient Kit

Routine filtration maintenance is an important part of protecting the performance, reliability, and service life of a diesel engine. The Fleetguard MK13066 Maintenance Kit provides a practical solution for servicing select Caterpillar diesel engines by grouping three essential replacement filters into one package.

Rather than purchasing individual filters separately, the MK13066 kit allows equipment owners, diesel mechanics, and fleet maintenance professionals to obtain the required filtration components together.

This maintenance package includes a Fleetguard LF3566 engine oil filter, FF5319 diesel fuel filter, and FS19807 fuel/water separator.

Fleetguard MK13066 Maintenance Kit Contents

One Fleetguard LF3566 Engine Oil Filter

The LF3566 lube filter is a heavy-duty, full-flow spin-on engine oil filter designed for diesel engine lubrication systems. This lube filter is designed to remove contaminants circulating through the engine lubrication system. Effective oil filtration helps reduce the exposure of internal engine components to abrasive particles and other unwanted materials carried in the lubricating oil.

One Fleetguard FF5319 Diesel Fuel Filter

The FF5319 fuel filter helps capture particulate contamination within the diesel fuel supply. Maintaining clean fuel is especially important for protecting sensitive fuel injection components and supporting dependable engine operation.

One Fleetguard FS19807 Fuel/Water Separator

The FS19807 fuel/water separator provides an additional layer of fuel system protection by helping remove water and contaminants from diesel fuel before they reach critical downstream components.
