FILTER FEATURES
Ethanol blended fuel absorbs more water and loosens more particulants than regular fuels. Proper filtration is
required for every horsepower engine. Sierra fuel water separators remove over 98.8% of emulsified water from your
gasoline. Sierra's 10 micron filters are over 90% efficient at removing particles as small as 10 micron. All filters
flow at 90 GPH to feed even the hungriest motor. Sierra 10 micron filters are recommended to prevent damage
to sensitive inboard and outboard fuel injection systems.
