It seals the mating surface between the fuel pump and its mounting point on the engine block, maintaining the seal needed to keep fuel flowing cleanly to the carburetor or fuel system without leaks, air intrusion, or pressure loss. A worn, cracked, or compressed original gasket is a common source of fuel pump seepage and rough running, and replacing it with the correctly sized 18-0849 restores a proper seal at a fraction of the cost of a new fuel pump assembly.\u003c\/p\u003e\u003cp\u003eThis gasket is designed to fit Yamaha Four-Stroke outboards from 9.9 hp through 300 hp, model year 1999 and newer. It cross-references directly to Yamaha OEM gasket and fuel pump numbers, so it installs in place of the original part without modification. Each unit ships as a single gasket, making it a simple, low-cost addition to a fuel pump service or rebuild kit for these outboards.\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 18-0849\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pump Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282291204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha Four-Stroke outboards, 9.9 hp - 300 hp, 1999 and newer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 904-30142-28-00, 90430-14228-00, 650-24431-A0-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha Four-Stroke outboards, 9.9 hp to 300 hp, 1999 and newer (Current)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e904-30142-28-00\u003c\/li\u003e\n\u003cli\u003e90430-14228-00\u003c\/li\u003e\n\u003cli\u003e650-24431-A0-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-0849 fuel pump mounting gasket fit?\u003c\/strong\u003e It fits Yamaha Four-Stroke outboards ranging from 9.9 hp to 300 hp, model year 1999 and newer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0849 a direct replacement for Yamaha part 650-24431-A0-00?\u003c\/strong\u003e Yes, the 18-0849 gasket cross-references directly to Yamaha 650-24431-A0-00 and installs as a direct replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM Yamaha numbers does part 18-0849 cross-reference?\u003c\/strong\u003e Sierra 18-0849 cross-references Yamaha numbers 904-30142-28-00, 90430-14228-00, and 650-24431-A0-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one order of 18-0849?\u003c\/strong\u003e Each order of the Sierra 18-0849 fuel pump mounting gasket includes a package quantity of 1 gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0849 gasket weigh?\u003c\/strong\u003e The Sierra 18-0849 fuel pump mounting gasket weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the fuel pump mounting gasket do?\u003c\/strong\u003e It seals the joint between the fuel pump and its mounting surface on the Yamaha outboard engine block, preventing fuel or air leaks at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-0849 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-0849 is a Sierra-branded aftermarket gasket manufactured to replace the equivalent Yamaha OEM gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill 18-0849 fit a Yamaha outboard built before 1999?\u003c\/strong\u003e The Sierra 18-0849 gasket is specified to fit Yamaha Four-Stroke outboards from model year 1999 and newer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0849 gasket?\u003c\/strong\u003e The UPC for Sierra fuel pump mounting gasket 18-0849 is 808282291204.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the fuel pump mounting gasket on my Yamaha outboard?\u003c\/strong\u003e Replace the 18-0849 gasket whenever the fuel pump is removed for service or if fuel seepage is visible at the pump mounting joint on a compatible Yamaha Four-Stroke outboard.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988085944539,"sku":"SIE-18-0849","price":2.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0849__61812.1772806444.500.750.jpg?v=1785188073"},{"product_id":"sierra-18-0850-9-fuel-pump-gasket-replaces-omc-303615-pack-of-2-evinrude-johnson-outboard","title":"Sierra Fuel Pump Gasket 18-0850-9, Replaces 303615, Pack of 2","description":"\u003cp\u003eThe Sierra 18-0850-9 Fuel Pump Gasket is a replacement gasket engineered for outboard fuel pump mounting applications, sold in a pack of 2 for convenient stocking or dual-side jobs.

Its aluminum construction is designed to hold up in the corrosive marine environment, and it is manufactured to meet or exceed the performance of the original equipment part it replaces.

Boat owners and marine technicians use this pump when replacing a worn or failing mechanical fuel pump on a compatible GM V-8 marine engine, restoring reliable fuel delivery to the carburetor.

Both parts are sized and shaped to match the original Yamaha fuel pump assembly, so the pump housing seals correctly and pumps fuel without bypass leakage once reassembled.

Yamaha outboard fuel pumps, built to meet or exceed the quality of the original equipment part it replaces. The diaphragm is the flexing rubber component inside the fuel pump body that draws fuel from the tank and pushes it toward the carburetor as the pump's actuating arm cycles; when it cracks, stretches, or loses its seal, the outboard can suffer from hard starting, poor fuel delivery, or a fuel leak at the pump housing. This diaphragm is made of rubber and is sized at 0.25 x 4 x 6.5 inches to fit into the pump housing correctly.\u003c\/p\u003e\u003cp\u003eSierra part 18-7837 is the correct diaphragm for Yamaha outboards using engine type 677 with serial numbers ML-677-316416 and up.
