Protect your fuel injectors and high-pressure fuel pumps from harmful contamination with the Genuine OEM Mercury / Quicksilver Under-Cowl Fuel Filter Assembly (Part # 35-8M0090809). Mounted under the motor cowl inside the low-pressure fuel line circuit, this high-efficiency filter captures dirt, rust, scale, and water droplets before they reach your vapor separator tank (VST) or delicate electronic fuel injection (EFI) components.

Engineered to handle the demands of modern ethanol-blended marine fuels, this factory replacement filter prevents fuel restriction, lean running conditions, and power loss. Replacing your under-cowl fuel filter every 100 hours or annually during routine maintenance is essential for keeping your engine running smooth, responsive, and reliable out on the water.
