Protect your engine’s fuel injection system and maintain peak horsepower with the Genuine OEM Mercury / Quicksilver In-Line Fuel Filter (Part # 35-879885Q01). Mounted under the engine cowl, this factory replacement filter screens out rust, scale, dirt, and water particles before they reach delicate fuel injectors, high-pressure pumps, or vapor separator tanks (VST).

Featuring a high-efficiency internal media housed inside a heavy-duty, chemical-resistant casing, this filter ensures steady fuel delivery without restrictive pressure drops. Replacing your fuel filter every 100 hours or annually during routine maintenance prevents fuel starvation, hard starting, and costly fuel system damage caused by ethanol-blended fuels or debris.
