We cleaned up your engine room, now clean up your boat’s transom!

The Walker FUELSEP® utilizes an advanced technology that improves the combustion of your diesel fuel for optimum engine performance and excellent fuel savings. The FUELSEP conditions the fuel to a higher level before combustion, so it burns cleaner, better, and more completely. As a result, you’ll substantially reduce the exhaust soot commonly deposited on the back of a diesel boat’s transom and cockpit area. You will help preserve your yacht’s expensive finish, and dramatically reduce the high cost and labor of bright work maintenance. 

This easy-to-install unit has a 5,000-hour/5 year life, the unit uses NO magnets, and is designed for all diesel or gas engines, gensets, and even outboard motors. FUELSEP technology has been US NAVY tested, and has a positive affect on all engines including Detroit Diesel®, Caterpillar®, Cummins®, Deutz®, Mercruiser, MTU®, Volvo® and Yanmar®.

If your diesel powered boat has a Walker AIRSEP system, then you know the FUELSEP is sure to work at making your engine a top performer. Gasoline powered engines will show similar high performance benefits.

So if you fuel your boat at different fuel docks, or in the islands where fuel quality might be questionable at best, then the FUELSEP is the best “insurance” you can buy.
