Product Overview

Industry leading canister fuel filters for outboard and inboard engines

High-performance fuel injected engines require ultimate fuel filtration, water spearation and maximum fuel flow. Sierra's new filter elements deliver all three of these critical performance factors. 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. Having an effective fuel filtration system will extend the life of the fuel pump and sensitive engine parts.

Sierra fuel filter/water separator kits include a compact coated aluminum filter head with 1/4" ports that can be in tight spaces. The included 7900-Series 10 micron filter eliminates harmful contaminants at over 90% efficiency, while removing over 99% of emulsified water. The included clear site bowl provides a visual indicator of fuel condition. Note, these filters are not recommended for installation in the engine room or other areas where exposure to high heat or flame is possible.
