Sierra Carburetor Needle and Seat Assembly Carburetors & Accessories

The Sierra Carburetor Needle and Seat Assembly is a replacement fuel inlet valve for marine and powersports carburetors. Also called a float needle valve or carburetor inlet needle and seat, it controls fuel flow into the float bowl and helps keep the fuel level correct for smooth running.

Key Features:

• Matched needle and seat assembly designed to seal fuel flow when the float rises
• Helps prevent flooding, fuel overflow, and rough idle caused by a worn or leaking inlet valve
• Aftermarket replacement built to match the original equipment design
• Suited to carburetor rebuilds, tune-ups, and routine maintenance
• Backed by Sierra's long-standing reputation in marine engine parts

Replacing a worn needle and seat can restore proper fuel delivery, improve starting and idle quality, and help protect against hard starting and fuel leaks. Choose the specific part number that matches your carburetor and engine.
