High-performance fuel injected engines require excellent fuel filtration, water separation and maximum fuel flow.

Sierra's 7900-Series 10 micron filters eliminate harmful contaminants at over 90% efficiency, while removing over 99% of emulsified water. They're engineered for today’s sterndrives and inboards, along with 2-cycle and 4-cycle outboards.

Because water is very soluble in alcohol, ethanol-blended fuels increase the chances of water in fuel tanks, resulting in premature wear, poor performance and component damage.
Contaminants of over 10 microns in size also can cause severe damage given the close tolerances of modern fuel pumps and injectors. That is why a high efficiency water separating filter is so important.
Sierra 10 micron filters have been independently tested to JIS, SAE J1839/J905 and ISO 4548-12 standards.

• Removes 99% of emulsified water from fuel
• Designed for the exact fit and specifications as OEM canister filters
• 90% efficient at removing particulate contamination
• Maintains fuel flow while filtering out harmful water and debris
• Max flow rate is a generous 90 gph
