The Problem

A diesel engine will collect dirt, water, varnishes, rust, and bacteria that will settle at the bottom of the tank. When the seas get rough the contaminants mix with the diesel fuel hence the need for fuel filters. When the fuel filter starts to clog the engine driven pump will naturally increase its vacuum to pull fuel through the filter, the fuel filter will eventually become totally clogged and will lead to engine shut down. This could happen in any number of sticky situations. Once the crew figures out that the fuel filter is clogged, they will have to change the filter and bleed the air out of the fuel system. This proves to be a tedious and dangerous task under poor sea conditions and creates the need for a more reliable filter system.

The Solution
The FILTER BOSS was designed to allow two filters to be installed, one online filter and one offline filter with a monitoring system and an integral pump system. The offline filter will be readily available when the online filter starts to clog, a crew member can select the filter by switching levers. A built in vacuum gage allows the crew to monitor the condition of the online filter. Additionally, the integral vacuum switch allows for the installation of a remote warning light. When the crew sees the filter starting to increase in vacuum (clog) or the warning light comes on, they will have the enough time to make the simple task of switching filters without shutting down the engine. Inside the FILTER BOSS is an electric fuel pump that will make engine bleeding and filter servicing a simple task.
The system can also be set up to act as an on-board fuel polishing system! You can now polish your fuel as often as you need to, when it is convenient for you!

“It really makes it simple to keep the fuel filters clean. I liked how easy it was to bleed the system and switch back to the first primary filter, keeping my second filter for emergencies. Fantastic!”
