It is designed for engines falling within two specific serial number ranges: F000455 to F273497 (1993-1994) and F273498 to F600999 (1994-1995). The kit is also compatible with MCM\/MIE\/Tow Sports 350 Mag and 5.7L\/LX engines running 9665 and 9781 Weber carburetors, and with MCM\/MIE 454 Mag 7.4L and 8.2L engines.\u003c\/p\u003e\u003cp\u003eBecause carburetors wear internally long before the outer housing does, a rebuild kit restores correct fuel metering and idle performance without the expense of a full carburetor replacement. The 18-7748 kit corresponds directly to the original Weber carburetor part numbers used on these engines and cross-references to a wide range of Carter\/Weber, Mallory, and Mercruiser OEM carburetor numbers, making it straightforward to match against an existing carburetor tag or an old kit part number.\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 18-7748\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor Rebuild Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor Compatibility:\u003c\/strong\u003e Weber 9665S (also fits 9665 and 9781 Weber carburetors)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Compatibility:\u003c\/strong\u003e 5.7L Alpha 350 V-8; MCM\/MIE 350 Mag and 5.7L\/LX engines; MCM\/MIE 454 Mag 7.4L and 8.2L engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial Number Range (1993-1994):\u003c\/strong\u003e F000455 to F273497\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial Number Range (1994-1995):\u003c\/strong\u003e F273498 to F600999\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5.7L Alpha 350 V-8, serial numbers F000455 to F273497 (1993-1994), Weber 9665S carburetor\u003c\/li\u003e\n\u003cli\u003e5.7L Alpha 350 V-8, serial numbers F273498 to F600999 (1994-1995), Weber 9665S carburetor\u003c\/li\u003e\n\u003cli\u003eMCM\/MIE\/Tow Sports 350 Mag and 5.7L\/LX engines with 9665 and 9781 Weber carburetors\u003c\/li\u003e\n\u003cli\u003eMCM\/MIE 454 Mag 7.4L and 8.2L engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e3310-806761A1\u003c\/li\u003e\n\u003cli\u003e3310-806761A3\u003c\/li\u003e\n\u003cli\u003eCarter\/Weber 9600, 9662, 9663, 9665, 9666, 9772, 9773, 9774, 9776, 9777, 9780, 9782, 9665S, 9772SA, 9776S, 9776SA, 9776SB, 9779S, 9780S\u003c\/li\u003e\n\u003cli\u003eMallory 9-37639\u003c\/li\u003e\n\u003cli\u003eMercruiser 809064, 8M0120193, 808697\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7748 carburetor kit fit?\u003c\/strong\u003e The Sierra 18-7748 fits 5.7L Alpha 350 V-8 engines with a Weber 9665S carburetor in two serial number ranges: F000455 to F273497 (1993-1994) and F273498 to F600999 (1994-1995).
