The kit contains two diaphragms, one 18-7842 Fuel Pump Diaphragm and one 18-7843 Fuel Pump Diaphragm, giving you both components needed to rebuild the fuel pump in a single package rather than sourcing each diaphragm separately.\u003c\/p\u003e\u003cp\u003eSierra builds this kit to meet or exceed the quality of the original equipment diaphragms it replaces, using precision-built components engineered to hold up in the marine environment. Sierra supplies parts to OEM engine manufacturers and boat builders, and this diaphragm kit is manufactured to the same fit and function standard as the factory originals it is designed to replace.\u003c\/p\u003e\u003cp\u003eThis is a compact, lightweight kit intended for outboard owners and marine technicians performing a fuel pump rebuild on applicable Yamaha outboard motors. Because it supplies both diaphragms in one kit, it simplifies ordering and ensures both wear components are replaced together during service.\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 18-7799\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Fuel Pump Diaphragm Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e (1) 18-7842 Fuel Pump Diaphragm and (1) 18-7843 Fuel Pump Diaphragm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\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 808282244842\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Yamaha outboard motor fuel pumps.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7799 Fuel Pump Diaphragm Kit include?\u003c\/strong\u003e The kit includes two diaphragms: one 18-7842 Fuel Pump Diaphragm and one 18-7843 Fuel Pump Diaphragm, giving you both components needed for a fuel pump rebuild in one package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-7799 kit fit?\u003c\/strong\u003e The Sierra 18-7799 Fuel Pump Diaphragm Kit is designed for Yamaha outboard motor fuel pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many diaphragms come in this kit?\u003c\/strong\u003e Two diaphragms are included, part numbers 18-7842 and 18-7843, both packaged together under Sierra part number 18-7799.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7799 kit genuine OEM or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket replacement kit engineered to meet or exceed the quality of the original equipment diaphragms it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7799 fuel pump diaphragm kit weigh?\u003c\/strong\u003e The Sierra 18-7799 Fuel Pump Diaphragm Kit weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the diaphragm kit?\u003c\/strong\u003e The Sierra 18-7799 kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I order the individual diaphragms separately instead of the full kit?\u003c\/strong\u003e The Sierra 18-7799 kit packages both the 18-7842 and 18-7843 diaphragms together as a single fuel pump diaphragm kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7799 kit?\u003c\/strong\u003e The UPC for the Sierra 18-7799 Fuel Pump Diaphragm Kit is 808282244842.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit come with gaskets or other fuel pump hardware?\u003c\/strong\u003e No, the Sierra 18-7799 kit contains only the two diaphragms, 18-7842 and 18-7843; no additional gaskets or hardware are included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace fuel pump diaphragms as a kit rather than one at a time?\u003c\/strong\u003e Since both diaphragms in a Yamaha outboard fuel pump wear together, the Sierra 18-7799 kit supplies both the 18-7842 and 18-7843 diaphragms at once so the entire wear set is replaced during a single rebuild.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988388131035,"sku":"SIE-18-7799","price":29.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7799_lg__90357.1558130177.500.750.jpg?v=1785188173","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7799-fuel-pump-diaphragm-kit-for-yamaha-outboards-contains-18-7842-18-7843-diaphragms","provider":"Good Vibes Marina","version":"1.0","type":"link"}
