It is designed to trap contaminants and debris in the fuel line before they reach the carburetor or fuel injection system, helping protect engine components from dirt, rust particles, and other fuel-borne impurities. The filter housing uses a stainless steel outer material for durability in the marine environment. This is a direct-fit replacement part intended for personal watercraft and outboard fuel systems that specify either the OMC or Suzuki part number above, making it a straightforward swap during routine maintenance or when replacing a clogged or aging filter. Each unit ships as a single fuel filter, ready to install in place of the original equipment part. Sierra manufactures this filter to the same part number used across OMC and Suzuki cross-references, so buyers searching by either OEM number will find this is the correct match.

The 18-7722 is designed as a direct replacement for OEM part number 5005266, so it installs in place of the original filter without modification. It is intended for Evinrude E-Tec 40, 50, 60, 75, 90, 115, 150, 175, and 200DPL outboard models. Each Sierra fuel filter is manufactured to meet or exceed the performance of the original equipment part it replaces, giving boat owners a reliable option for routine 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 18-7722\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb Size:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Rating:\u003c\/strong\u003e 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 5005266\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Evinrude E-Tec 40, 50, 60, 75, 90, 115, 150, 175 \u0026amp; 200DPL outboards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Evinrude E-Tec 40, 50, 60, 75, 90, 115, 150, 175, and 200DPL outboard engines.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003e5005266\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7722 fuel filter fit?\u003c\/strong\u003e The 18-7722 is designed for Evinrude E-Tec 40, 50, 60, 75, 90, 115, 150, 175, and 200DPL outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does this filter replace?\u003c\/strong\u003e This fuel filter replaces OEM part number 5005266 and installs as a direct swap for the original filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size fuel line does the 18-7722 use?\u003c\/strong\u003e It has 3\/8 inch barb fittings on both ends, matching standard 3\/8 inch marine fuel line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the micron rating of this fuel filter?\u003c\/strong\u003e The Sierra 18-7722 has a 27 micron filter rating, which catches fine dirt and debris before it reaches the fuel system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuel filter housing made of?\u003c\/strong\u003e The 18-7722 housing is made of plastic, built to withstand engine compartment conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7722 fuel filter weigh?\u003c\/strong\u003e It weighs 0.12 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7722 a genuine OEM part or aftermarket?\u003c\/strong\u003e The 18-7722 is a Sierra-manufactured replacement filter, engineered to meet or exceed the performance of the original 5005266 equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7722 fit any outboard other than Evinrude E-Tec models?\u003c\/strong\u003e The 18-7722 is built for Evinrude E-Tec 40 through 200DPL outboards; check the fitment list before ordering for other engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-7722 fuel filter?\u003c\/strong\u003e The 18-7722 fuel filter housing is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if I need to replace my fuel filter?\u003c\/strong\u003e Rough running, stalling, or reduced power on an Evinrude E-Tec outboard can indicate a clogged fuel filter; the 18-7722 replaces the original 5005266 filter as routine maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7722 come as a single filter or a set?\u003c\/strong\u003e The 18-7722 is sold as a single fuel filter unit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988387115227,"sku":"SIE-18-7722","price":11.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7722_lg__44101.1558131926.500.750.jpg?v=1785188370"},{"product_id":"marine-fuel-filter-for-johnson-evinrude-suzuki-4-stroke-outboards-replaces-omc-5032238-suzuki-15410-98500-sierra-18-7719","title":"Sierra Fuel Filter 18-7719, Replaces OMC 5032238 and Suzuki 15410-98500, 140 Micron","description":"\u003cp\u003eThe Sierra 18-7719 is a replacement fuel filter for outboard engines, designed to trap contaminants before they reach the carburetor or fuel injection system.

This filter is built as a direct interchange for the Johnson\/Evinrude Outboard 5032238 filter and the Suzuki Outboard 15410-98500 filter, so it fits applications originally equipped with either of those OEM parts. It ships as a single unit, ready to install in place of the worn factory filter during routine fuel system maintenance. Sierra parts are backed by Sierra's customer satisfaction warranty, giving boat owners confidence when replacing critical fuel system components. Because clogged or degraded fuel filters are a common cause of poor engine performance on outboards, keeping this filter fresh is a routine but important part of engine upkeep.

It removes over 99.8% of emulsified water from gasoline before it reaches the engine, protecting fuel system components from water contamination that can cause stalling, corrosion, and injector damage. The filter media is rated at 10 microns and is over 90% efficient at capturing particles as small as 10 microns, catching rust, dirt, and debris that would otherwise pass through to sensitive fuel injection components. Rated to flow at 90 gallons per hour, the 18-7829 is built to keep up with demanding engines without restricting fuel delivery.\u003c\/p\u003e\u003cp\u003eThis filter is specifically recommended for use ahead of inboard and outboard fuel injection systems, where even small amounts of water or particulate contamination can cause costly damage. The large capacity design of the 18-7829 gives it more dirt-holding capacity and longer service intervals than smaller separators, making it a good choice for boats that see heavy use or run in less-than-clean fuel conditions.
