water fuel separator filter for outboard motors


Tohatsu Water / Fuel Separator Filter

Easily connected between your fuel tank and engine, the 10 micron filter traps over 98% of the water that may be present in the fuel tank before it reaches your engine. This prevents moisture from damaging the critical engine parts such as the electric fuel feed pump and the fuel injection system or carburetors.  This is especially important with today's ethanol based fuels which attracts water more easily than regular fuels.
