It draws fuel from the tank and delivers it to the carburetor at the pressure and volume the powerhead requires, restoring reliable starting and steady running on engines whose original pump has worn out, developed a diaphragm leak, or lost priming pressure.\u003c\/p\u003e\u003cp\u003eThe pump body is constructed of aluminum for corrosion resistance in the marine environment, with mechanically threaded NPT inlet and outlet connections for a secure fuel-line fit. It is a direct cross to the OMC 433386 and 438555 fuel pumps used on this engine range, and pairs with Sierra service kit 18-7800 when a rebuild rather than full pump replacement is preferred. Each Sierra fuel pump is manufactured to meet or exceed the performance of the original equipment part it replaces.\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 18-7353\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 438555, 433386\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Johnson\/Evinrude 20-30 HP outboards, 1990-2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Service Kit:\u003c\/strong\u003e 18-7800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet\/Outlet Connection:\u003c\/strong\u003e Mechanical Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.36 pounds\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\u003eUPC:\u003c\/strong\u003e 808282111557\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboards, 20-30 HP, 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 engines does the Sierra 18-7353 fuel pump fit?\u003c\/strong\u003e The 18-7353 is built for Johnson\/Evinrude outboards rated 20-30 HP for the 1990-2000 model years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-7353 replace?\u003c\/strong\u003e It replaces OMC 433386 and 438555, so either number can be used to confirm the 18-7353 is the correct match for your outboard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-7353 is a Sierra-branded replacement fuel pump manufactured to meet or exceed the performance of the original OMC 433386\/438555 pump it replaces, not a generic knockoff.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuel pump body made of?\u003c\/strong\u003e The Sierra 18-7353 has an aluminum pump body, chosen for its corrosion resistance in marine use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the fuel line connect to the 18-7353?\u003c\/strong\u003e Inlet and outlet connections are mechanically threaded NPT fittings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7353 fuel pump weigh?\u003c\/strong\u003e It weighs 0.36 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-7353?\u003c\/strong\u003e The pump measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I rebuild my existing pump instead of replacing it?\u003c\/strong\u003e Yes, Sierra service kit 18-7800 is the compatible kit for rebuilding a pump in the same 20-30 HP, 1990-2000 Johnson\/Evinrude application as the 18-7353.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with the 18-7353?\u003c\/strong\u003e The listing includes one complete Sierra 18-7353 fuel pump, ready for direct installation in place of the worn OMC 433386\/438555 unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace my outboard's fuel pump?\u003c\/strong\u003e A worn diaphragm or failing seals in the original OMC pump causes hard starting, stalling, or loss of fuel pressure; the Sierra 18-7353 restores factory-level fuel delivery on qualifying 20-30 HP Johnson\/Evinrude engines.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988384297179,"sku":"SIE-18-7353","price":63.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-7353__88678.1739458959.500.750.jpg?v=1785188657","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-fuel-pump-for-johnson-evinrude-20-30-hp-1990-2000-outboards-replaces-omc-433386-438555-sierra-18-7353","provider":"Good Vibes Marina","version":"1.0","type":"link"}
