Its primary job is to screen contaminants and debris out of the fuel supply before they reach the carburetor, protecting jets and internal fuel system components from clogging and premature wear caused by dirt, rust, or water in the fuel. The filter uses a metal outer housing designed to hold up in the demanding marine environment, resisting the corrosion and vibration that outboard engines are exposed to on the water.\u003c\/p\u003e\u003cp\u003eFiltration is rated at 27 microns, giving it a fine enough screen to catch the small particulate that commonly causes rough idle, hesitation, or stalling in carbureted fuel systems. As a Sierra part, it is built to meet or exceed the performance of the original equipment part it replaces, and Sierra supplies filters of this type to OEM engine manufacturers and boat builders. Each unit ships as a single fuel filter ready for direct installation in place of the factory filter on compatible engines. It is backed by Sierra's customer satisfaction warranty, giving boat owners confidence in a straightforward, drop-in replacement for scheduled fuel system maintenance.\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 18-7979\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Fuel Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Rating:\u003c\/strong\u003e 27 microns\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Material:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Mercury\/Mariner 75\/90\/115 hp FourStroke carbureted outboards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282201043\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 count\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Boat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury\/Mariner 75\/90\/115 hp FourStroke carbureted outboards\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7979 fuel filter fit?\u003c\/strong\u003e The Sierra 18-7979 fits Mercury\/Mariner 75, 90, and 115 hp FourStroke carbureted outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7979 a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e It is a genuine Sierra fuel filter, engineered to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat micron rating does this fuel filter have?\u003c\/strong\u003e 27 microns, which is the filtration rating for the Sierra 18-7979 fuel filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the filter housing made of?\u003c\/strong\u003e The Sierra 18-7979 has a metal outer housing, built to hold up in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-7979 fuel filter weigh?\u003c\/strong\u003e 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this filter?\u003c\/strong\u003e One Sierra 18-7979 fuel filter ships per unit, ready for direct installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7979 work on fuel-injected Mercury outboards?\u003c\/strong\u003e The Sierra 18-7979 is specified for Mercury\/Mariner 75\/90\/115 hp FourStroke carbureted outboards, not a fuel-injected application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this fuel filter covered by a warranty?\u003c\/strong\u003e Yes, the Sierra 18-7979 is backed by Sierra's customer satisfaction warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the 18-7979 fuel filter?\u003c\/strong\u003e Follow your Mercury\/Mariner engine owner's manual service interval for fuel filter replacement to keep the fuel system protected.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7979 fuel filter?\u003c\/strong\u003e 808282201043 is the UPC for the Sierra 18-7979 fuel filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7979 fit a Mariner-branded outboard as well as Mercury?\u003c\/strong\u003e Yes, the Sierra 18-7979 is specified to fit both Mercury and Mariner 75\/90\/115 hp FourStroke carbureted outboards.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988426961115,"sku":"SIE-18-7979","price":15.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7979_lg__86235.1558132776.500.750.jpg?v=1785188046","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7979-fuel-filter-for-mercury-mariner-75-90-115-hp-fourstroke-outboards-replaces-881540-10-micron","provider":"Good Vibes Marina","version":"1.0","type":"link"}
