    Average Customer Review for Fuel Water Separator Filter - Sierra
    Based On 2 Reviews
    Sierra Fuel/Water Separator by Andrew - Rogers, OhioMay 01, 2012
    With gasoline now contaning 10% ethanol, removing water from the fuel is important. Ethanol attracts moisture from the air, and moisture in the engine is bad news. I've used Sierra fuel/water separators for years, and never had any such related problems with water. They should be changed yearly, more frequently if you run more than the average.

    Filter kit with Housing by Michael - Prattville, AlabamaJune 13, 2011
    Bought this for use on my small boat, because they worked so well on my big boat. Easy to install, uses the same 10 micron filter. Just got it in last week, so I look forward to seeing if they work just as well. Got a filter kit with two filters for less than I could get just the housing locally.
