Better fuel Filtration Born from Necessity

As they say, "Necessity is the father of invention." These words certainly rang true when we decided to start Keenan Filters. 

About 25 years ago we bought a sailboat with a diesel engine and immediately found out it had serious fuel system problems. After our first year, we had experienced multiple unexpected engine shutdowns and spent countless messy hours crawling around the engine troubleshooting. Each attempted repair also inevitably ended with a messy priming exercise to get the fuel system back up and running to see if our repair had worked. As our frustration mounted, we decided to search for a whole system solution to our problems. 

We were looking for more than a basic fuel filter. What we wanted was a complete diesel fuel maintenance system that would allow us to switch to a clean filter without stopping the motor, bleed and prime the system without the need for an external fuel source, and work as a backup fuel pump if needed. Our search turned out to be futile. After several months of researching options, we realize that no such system existed.  So we decided to create one. 

Our original FilterBoss design was the result of those efforts. It combined twin Racor® turbine filters, connected to a manifold, and included a separate fuel pump to fill the bowls and clean the stored fuel already in the system. We also developed a remote location warning and switching panel, so that we could learn of potential problems from the cockpit before the engine shut down and change to a clean filter with the flick of a switch. 

It worked beautifully! After we installed the system to our old boat we never had to worry about fuel issues again. We also realized that we had a commercially viable diesel fuel filtration and management system. Now, several patents later, Keenan Filters offers a wide array of sizes and system options that ensure reliably clean fuel delivery to almost any size diesel fuel engine, no matter the use. From 60 gallons per hour (GPH) to 1500 GPH, we offer the best way to manage your entire diesel fuel system and eliminate the number one reason for unexpected diesel motor shut down: dirty fuel. 

Is your fuel Keenan clean?
