Sierra 18-7200 Carburetor Float, Replaces Mercruiser 1397-2060, for GM 4.3/262 and 5.0L Rochester 2GE Carburetors

The Sierra 18-7200 is an alcohol-resistant carburetor float built for marine Rochester 2GE carburetors used on GM 4.3/262 and 5.0L inboard/sterndrive engines. It is constructed of marine-grade plastic that resists degradation from ethanol-blended fuels, a common failure point for original equipment floats exposed to modern pump gas. The float works with the Mfg. Code R2 Rochester 2GE carburetor and is paired with Sierra carburetor kit 18-7086 for a complete rebuild.

Each Sierra 18-7200 float is manufactured to meet or exceed the specification of the original equipment part it replaces, and it cross-references directly to AC Delco, Crusader, EMP, GLM, Mercruiser, OMC, and Volvo Penta float part numbers, so it can be used as a like-for-like replacement during a carburetor rebuild or float-related repair. Because float fit and buoyancy are critical to correct fuel metering, always confirm the carburetor model and engine application against your existing float before installing.
