It is built to meet or exceed the quality of the original equipment part it replaces, giving boaters a reliable, drop-in seal for carburetor servicing or replacement work. This gasket is the designated replacement gasket for the remanufactured Universal Q-jet carburetor with electric choke, and it is commonly paired with carburetor rebuild work on that same unit.\u003c\/p\u003e\u003cp\u003eUsing the correct mounting gasket is critical to preventing vacuum leaks, fuel leaks, and rough idle or stalling caused by a poor seal between the carburetor base and the intake manifold. The Sierra 18-0462 is manufactured to precise dimensions so it seats correctly without the trimming or fitting issues sometimes seen with generic gaskets. It cross-references directly to GLM 31540, Mallory 9-61003, and Mercruiser 27-48399, making it a straightforward replacement for boaters who already have one of those part numbers specified for their engine.\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 18-0462\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e GLM 31540, Mallory 9-61003, Mercruiser 27-48399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Carburetor:\u003c\/strong\u003e Universal Q-jet Carburetor with Electric Choke (Remanufactured)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with the Universal Q-jet carburetor with electric choke (remanufactured).
