Sierra 18-7989 Spin-On Fuel Filter; 10 Micron

Industry leading canister fuel filters for outboard and inboard engines

High-performance fuel injected engines require the ultimate fuel filtration; water separation and  maximum fuel flow. Sierra's new filter elements deliver all three of these critical performance factors. 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.

Ethanol-blended fuels increase the chances of water in fuel tanks; resulting in premature wear; poor performance and component damage. Contaminants of over 10 micron size also can cause severe damage with 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 were independently tested to JIS; SAE J1839/J905 and ISO 4548-12 standards.
