It removes over 99.8 percent of emulsified water from gasoline and is over 90 percent efficient at removing particles as small as 10 micron, while still flowing 90 gallons per hour to keep fuel delivery adequate for high-demand engines. This High Capacity filter measures 6 inches (152.4 mm), giving it more media surface area and longer service intervals than Sierra's Compact 10 Micron and Short\/Long 21 Micron filter options.\u003c\/p\u003e\u003cp\u003eThe 18-7866 is a direct equivalent for the Yamaha MAR-FUELF-IL-TR fuel filter, making it a straightforward replacement when servicing fuel systems that call for that part number. Regular replacement of the fuel water separator is a key maintenance step for preventing water-related damage to injectors, carburetors, and fuel pumps in marine engines.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7866\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDescription:\u003c\/strong\u003e High Capacity Fuel Water Separator Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Size:\u003c\/strong\u003e High Capacity - 6 inches (152.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Rating:\u003c\/strong\u003e 10 Micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate:\u003c\/strong\u003e 90 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Removal:\u003c\/strong\u003e Removes over 99.8% of emulsified water from gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle Filtration:\u003c\/strong\u003e Over 90% efficient at removing particles as small as 10 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e Yamaha MAR-FUELF-IL-TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Material:\u003c\/strong\u003e Aluminum or Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282187330\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha fuel systems specified for the MAR-FUELF-IL-TR filter\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMAR-FUELF-IL-TR\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7866 fuel filter replace?\u003c\/strong\u003e The Sierra 18-7866 is a direct equivalent for the Yamaha MAR-FUELF-IL-TR fuel water separator filter, so it can be used wherever that part number is specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much water can this filter remove from fuel?\u003c\/strong\u003e It removes over 99.8 percent of emulsified water from gasoline, which is the primary function of the 18-7866 High Capacity fuel water separator filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat micron rating is the 18-7866 filter?\u003c\/strong\u003e 10 micron.
