Sierra 18-7920 Spin-On Fuel Filter; 10 Micron


Industry leading canister fuel filters for outboard and inboard engines with bowls

High-performance fuel injected engines require ultimate water separation; fuel filtration and maximum fuel flow. Sierra's new filter elements deliver all three of these critical performance factors and are engineered for today’s sterndrives; inboards; and 2-cycle and 4-cycle outboards.

Ethanol-blended fuels hold more water and can increase the chances of water in fuel tanks; resulting in premature wear; poor performance and component damage. Sierra 7900 Series fuel filters are designed to successfully remove 99% of the emulsified water found in fuels. Contaminants over 10 microns can cause severe damage in close tolerance modern fuel pumps and injectors; Sierra filters have 90% efficiency rate of removing these harmful contaminates while maintaining fuel flow rates to meet the demands of modern high performance engines.
