Each unit is flow tested across the entire throttle range before it leaves the factory, and the fuel mixture and idle settings are preset so that only minor idle and choke adjustments are typically needed at installation. The finish is machined for a clean, precise fit at the mounting flange.\u003c\/p\u003e\u003cp\u003eThis carburetor is built for 1998 and newer 5.7L applications, and covers MCM 5.7L engines within serial number range 0L010037-0W300754 as well as MIE\/Tow Sports 5.7L engines within serial number range 0L002003-0W090899. A base gasket is included with the carburetor, and Sierra specifies gasket 18-0994 as the replacement gasket for future service. The 18-7376N is designed to meet or exceed OEM specifications for fit, function, and durability.\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 18-7376N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e New anodized aluminum casting (non-remanufactured)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Carburetor with base gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Gasket:\u003c\/strong\u003e 18-0994\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282339920\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1998 and newer 5.7L applications\u003c\/li\u003e\n\u003cli\u003eMCM 5.7L, serial numbers 0L010037-0W300754\u003c\/li\u003e\n\u003cli\u003eMIE\/Tow Sports 5.7L, serial numbers 0L002003-0W090899\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e3310-864943A01\u003c\/li\u003e\n\u003cli\u003e3310-861245A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7376N carburetor fit?\u003c\/strong\u003e The 18-7376N is built for 1998 and newer 5.7L applications, covering MCM 5.7L engines in serial number range 0L010037-0W300754 and MIE\/Tow Sports 5.7L engines in serial number range 0L002003-0W090899.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a gasket included with the 18-7376N carburetor?\u003c\/strong\u003e Yes, the Sierra 18-7376N ships with its base gasket included, so no separate gasket purchase is needed for the initial installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-7376N replace?\u003c\/strong\u003e It replaces OEM numbers 3310-864943A01 and 3310-861245A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7376N a new or remanufactured carburetor?\u003c\/strong\u003e It is a new, non-remanufactured unit built on a new anodized aluminum casting, not a rebuilt core.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-7376N carburetor made of?\u003c\/strong\u003e The carburetor body is a new anodized aluminum casting with a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7376N need adjustment after installation?\u003c\/strong\u003e The fuel mixture and idle settings on the 18-7376N are preset from the factory, so typically only minor idle and choke adjustments are needed after it is installed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-7376N carburetor weigh?\u003c\/strong\u003e The 18-7376N weighs 4.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat gasket should I use if I need to replace the one included with the 18-7376N?\u003c\/strong\u003e Sierra specifies gasket 18-0994 as the replacement gasket for the 18-7376N carburetor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs every 18-7376N carburetor tested before it ships?\u003c\/strong\u003e Yes, each 18-7376N is flow tested throughout the entire throttle range before leaving the factory.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7376N meet OEM specifications?\u003c\/strong\u003e The 18-7376N is designed to meet or exceed OEM specifications for fit, function, and performance on its listed 1998-and-newer 5.7L applications.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988384592091,"sku":"SIE-18-7376N","price":404.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7376N__13268.1753450422.500.750.jpg?v=1785188610","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7376n-marine-carburetor-for-1998-newer-mercruiser-5-7l-replaces-3310-864943a01-new-aluminum-casting","provider":"Good Vibes Marina","version":"1.0","type":"link"}
