Sierra fuel water separators remove over 98.8% of emulsified water from gasoline. Sierra's 10 micron filters are over 90% efficient at removing particles as small as 10 micron. Ethanol blended fuel absorbs more water and loosens more particulants than regular fuels. All filters flow at 90 GPH. ONLY SUITABLE FOR ABOVE DECK APPLICATIONS. USCG requires a flame resistant metal bowl for below deck applications.

Sierra Aqua Vue and metal collection bowl separator filters allow water to be drained from the filter to extend service life. Use the Aqua Vue collection bowl for outboard, above deck installations. USCG regulations require the use of the flame resistant metal collection bowl below deck. Kit contains 2 brass pipe plugs. Display packaged.
