The Tohatsu 9999979321M Water/Fuel Separator Kit with AquaVue Bowl provides critical protection for your outboard engine’s fuel system. This complete separator kit removes an impressive 98.8% of emulsified water from your fuel supply, preventing moisture from damaging sensitive components like electric fuel pumps, fuel injection systems, and carburetors. Designed and recommended for all two-stroke and four-stroke gasoline engines, this universal kit delivers essential protection across the entire Tohatsu outboard lineup.

The kit’s standout feature is the transparent AquaVue bowl, which allows instant visual inspection of collected water and debris without disassembly. This clear bowl makes monitoring easy, so you know exactly when maintenance is required. The included 10-micron filter captures particles and contaminants while the advanced design separates water through density differences, causing water droplets to settle in the visible collection bowl. Rated for 90 gallons per hour, this separator handles flow requirements from small portable outboards to larger high-horsepower models without restricting fuel delivery.

Installation between your fuel tank and engine is straightforward, and the included o-ring ensures leak-free operation. Regular inspection through the AquaVue bowl and periodic filter replacement keep your fuel system clean and your engine running reliably. Water in fuel causes poor performance, hard starting, and potential engine damage, making this separator essential protection for your investment. Northeast Marine stocks both the complete Water/Fuel Separator Kit with AquaVue Bowl and replacement filters to keep your Tohatsu protected from fuel contamination.
