It is designed as a direct equivalent to the original equipment fuel pump, replacing OEM numbers 438555 and 433386 so the pump can be rebuilt in place rather than replaced as a whole assembly.\u003c\/p\u003e\u003cp\u003eThe kit contains the parts needed to restore fuel pump function: two check valves (18-7796), two O-rings (18-7413 and 18-7403), and a fuel pump gasket (18-0850). These components seal and regulate fuel flow through the pump body, and replacing them addresses common fuel pump issues such as loss of prime, fuel leaks, and inconsistent fuel delivery caused by worn seals and check valves. Each component is precision-built to fit the pump housing it is designed for.\u003c\/p\u003e\u003cp\u003eThis kit is intended for outboard owners and marine technicians performing a fuel pump rebuild rather than a full pump replacement, and it is sized and packaged as a lightweight kit for straightforward installation during 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 18-7800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 20-30 HP Johnson\/Evinrude outboard motors, 1990-2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 438555, 433386\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e (2) Check Valve 18-7796, (1) O-Ring 18-7413, (1) O-Ring 18-7403, (1) Fuel Pump Gasket 18-0850\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e20-30 HP Johnson\/Evinrude outboard motors, 1990-2000\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e438555\u003c\/li\u003e\n\u003cli\u003e433386\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard motors does the Sierra 18-7800 fuel pump kit fit?\u003c\/strong\u003e The 18-7800 kit fits Johnson\/Evinrude outboard motors rated 20-30 HP for the 1990-2000 model years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-7800 kit replace?\u003c\/strong\u003e It replaces OEM numbers 438555 and 433386, allowing the fuel pump to be rebuilt without sourcing the original manufacturer part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a full fuel pump or a rebuild kit?\u003c\/strong\u003e It is a rebuild kit for the existing fuel pump, not a complete replacement pump assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat parts are included in the 18-7800 kit?\u003c\/strong\u003e The kit includes two check valves (18-7796), two O-rings (18-7413 and 18-7403), and a fuel pump gasket (18-0850).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7800 fuel pump kit weigh?\u003c\/strong\u003e The kit weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the fuel pump kit packaging?\u003c\/strong\u003e The kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this kit work on a different horsepower outboard?\u003c\/strong\u003e The 18-7800 kit is designated for 20-30 HP Johnson\/Evinrude motors from 1990-2000; other horsepower ranges use different Sierra fuel pump kits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a fuel pump gasket included with the kit?\u003c\/strong\u003e Yes, one fuel pump gasket (18-0850) is included along with the check valves and O-rings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate this fuel pump kit is needed?\u003c\/strong\u003e Loss of engine prime, fuel leaks around the pump, or inconsistent fuel delivery typically indicate worn check valves, O-rings, or a gasket, which the 18-7800 kit addresses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7800 kit include the pump housing itself?\u003c\/strong\u003e No, the kit contains the internal seal components (check valves, O-rings, and gasket) used to rebuild an existing fuel pump housing, not the housing itself.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988388065499,"sku":"SIE-18-7800","price":20.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7800_lg__25032.1558130236.500.750.jpg?v=1785189156","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7800-fuel-pump-kit-for-johnson-evinrude-9-9-15-hp-outboard-1993-2006-replaces-omc-438616-433519","provider":"Good Vibes Marina","version":"1.0","type":"link"}
