Sierra Fuel/Water Separator
by Andrew from Rogers, Ohio on May 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.

21 Micron filter
by Emmett from Pearland, Texas on April 26, 2013
This is labeled as a replacement for the Mercury 35-802893Q, but when received the specs reflect it is a 21 Micron filter! NOT the 10 Micron filer I need. I had looked for the specs on-line before ordering and they were not listed. The 10 Micron P/N is 18-7945 according to the West Marine website.

Sierra Filters Work Great
by Michael from Prattville, Alabama on June 13, 2011
I switched to the 10 micron fuel/water separator filter in 2008 and have had great service from them. I change them every 50 hours and keep spares on the boat. I've never had a clog and I don't have issues with the 10% ethanol fuel I'm running. Great price too!
