Compact. Reliable. Proven.

The FilterBoss series is the heart of Keenan Filters, built to deliver clean fuel and dependable performance for a wide range of diesel engines. Whether your engine powers a coastal cruiser, a work vessel, or an offshore yacht, these systems offer a smarter, safer way to manage diesel fuel, from essential filtration to full featured priming, polishing, and filter switching.

Every FilterBoss system is designed to prevent the most common cause of diesel engine shutdown, which is contaminated fuel, by combining advanced multi stage filtration, high quality components, and intelligent monitoring. They do more than filter. They polish the fuel to remove water, sludge, and particulates before they reach your engine, extending the life of critical components and reducing maintenance costs.

Each configuration shares the same rugged build quality and filtration performance, but with features tailored to different needs.
