How do you install a fuel water separator? Install the head unit vertically, above bilge water, between the tank and engine (or primer bulb if on an outboard). The hoses should reach the engine and tank without kinking or making sharp turns. Drill pilot holes in the mounting point, inject sealant and fasten with self-tapping stainless-steel screws.
Do you put fuel in a fuel water separator? Should You Pre Fill A Boat Fuel Filter or Water Separator? Yes, pre-filling a boat’s fuel filter or water separator is a great habit. You won’t cause any harm to the engine and it will make your engines fuel lift pumps job much easier. This eliminates the introduction of a large amount of air into the fuel system.
How does a fuel and water separator work? How Does a Fuel/Water Separator Work? A centrifuge which spins the fuel (although there are no moving parts in the filter itself) such that the denser component (water) is thrown to the outside of the centrifuge and drops into the collection bowl at the bottom of the unit. The fuel then moves upward through a filter.
Do boats need a fuel water separator? Water can get in through the cap, a defective vent, or sometimes there’s water in the fuel when you get it from the gas station. The best way to make sure you protect your boat engine is to have a separator installed on the fuel line to make extra sure you’re not feeding your engine contaminated fuel.

What does drain water separator mean?
Diesel fuel can easily become contaminated by water because diesel fuel absorbs water more than gasoline does. For this reason, many diesel vehicles feature a gadget called a water separator that collects water from the fuel. It’s usually located on or near the fuel filter.
Do 2 stroke outboards have fuel filters?
