This is the same base gasket that Sierra includes with every one of its remanufactured carburetors, and it is also used together with Sierra Carb Kit 18-7070 when performing a full carburetor rebuild. Installing a fresh mounting gasket during any carburetor removal, rebuild, or replacement is essential to prevent air and fuel leaks at the base of the carburetor, which can cause rough idle, poor fuel efficiency, and inconsistent engine performance.\u003c\/p\u003e\u003cp\u003eEach gasket is sold as a single unit and is built to the same fit and material specification as the original equipment gasket it replaces. Because it directly cross-references several OEM and OEM-equivalent part numbers, it is a straightforward drop-in replacement for boat owners and marine technicians servicing Rochester 2 barrel carburetor setups.\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 18-0356\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carb Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Carburetor Type:\u003c\/strong\u003e Rochester 2 barrel carburetor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e Sierra Carb Kit 18-7070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999873439\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 1347-818620, 13478186201, 1347-818620R02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Rochester 2 barrel carburetors.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003e1347-818620, 13478186201, 1347-818620R02\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat carburetors does the Sierra 18-0356 gasket fit?\u003c\/strong\u003e The Sierra 18-0356 is a base mounting gasket designed for Rochester 2 barrel carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0356 gasket included with a full carburetor rebuild kit?\u003c\/strong\u003e Yes, this gasket is used together with Sierra Carb Kit 18-7070 when performing a complete carburetor rebuild, and it is also the same base gasket included with every Sierra remanufactured carburetor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does Sierra 18-0356 cross-reference?\u003c\/strong\u003e It replaces OEM numbers 1347-818620, 13478186201, and 1347-818620R02.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one order of part number 18-0356?\u003c\/strong\u003e Each order includes a single Carb Mounting Gasket, matching the unit count of 1 for this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does a carburetor need a base mounting gasket?\u003c\/strong\u003e A base mounting gasket like the 18-0356 seals the joint between the carburetor and the intake manifold to prevent air and fuel leaks that can cause rough idle or poor performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0356 gasket weigh?\u003c\/strong\u003e The Sierra 18-0356 Carb Mounting Gasket weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0356 an OEM or aftermarket part?\u003c\/strong\u003e It is an aftermarket gasket manufactured by Sierra that is built to match the fit of the OEM base gasket it replaces on Rochester 2 barrel carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the carburetor base gasket?\u003c\/strong\u003e Anytime the carburetor is removed, rebuilt, or replaced, the base gasket, such as the Sierra 18-0356, should be replaced to ensure a proper seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0356 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0356 Carb Mounting Gasket is 030999873439.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0356 gasket work on its own without a full rebuild kit?\u003c\/strong\u003e Yes, the 18-0356 can be purchased and installed on its own as a replacement base gasket, or used alongside Sierra Carb Kit 18-7070 during a complete rebuild.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988072673499,"sku":"SIE-18-0356","price":7.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0356_lg__55399.1558118960.500.750.jpg?v=1785188282","url":"https:\/\/www.goodvibesmarina.com\/products\/carb-mounting-gasket-for-rochester-2-barrel-replaces-mercruiser-27-64692-fits-mercruiser-crusader-454","provider":"Good Vibes Marina","version":"1.0","type":"link"}
