OEM Fuel Filters

Protecting your engine’s precise fuel injection system requires an absolute defense against micro-debris. These genuine Yamaha under-cowl fuel filters are mounted directly inside the engine cowling to act as the final line of defense for your powerhead. Engineered specifically to handle the high-volume flow rates of modern four-stroke outboards, these filters catch fine rust particles, line scale, and storage tank sediment that easily pass through coarse fuel station pumps.

Constructed with high-grade, chemical-resistant resin housings and specialized media elements, these factory-spec components will not warp, degrade, or restrict fuel pressure under intense heat and continuous fuel pressure. Utilizing a highly dense pleated paper structure, they trap debris down to a microscopic level while maintaining an unrestricted fuel flow curve. Regularly replacing your inline filter prevents injector clogging, stabilizes high-RPM fuel distribution, and protects high-pressure vapor separators from premature failure.

Variants Available:

• Inline Strainer Elements: Compact, clear-body inline filters designed for lightweight portables and mid-range 2-to-4 cylinder blocks.

• Spin-On & Under-Cowl Element Assemblies: High-capacity pleated elements built to snap directly into the factory onboard bracket arrays of large V6 and V8 offshore platforms.

Key Features:

• High-density pleated filter media optimized for maximum surface area and minimal flow restriction

• Clear-view high-impact housing on specific models for instant, visual contamination tracking

• Chemical-resistant seals designed to prevent vapor leaks in volatile engine environments

• Calibrated micron filtration ratings to match specific factory injector screen specifications

Ideal For: Scheduled 100-hour or annual marine maintenance intervals, correcting mid-range engine hesitation, and replacing stained or debris-choked factory filters.
