What This Carburetor Float Does
The carburetor float works together with the needle and seat assembly to control fuel level inside the carburetor bowl.
Maintaining correct fuel level helps provide proper idle quality, throttle response, fuel delivery, and reliable engine operation.
Over time, floats may absorb fuel, become damaged, or lose buoyancy, which may lead to flooding or poor carburetor performance.
Replacing worn carburetor floats during carburetor service helps restore proper fuel system operation.

What This Part Is Used For
Fuel injector O-rings help seal the injector properly when installed in the fuel rail or intake system. If an injector is removed for cleaning, inspection, or replacement, installing a new O-ring helps ensure the system seals correctly when reassembled.
Over time these seals can flatten, harden, or become damaged due to heat and fuel exposure. Replacing them during injector service helps prevent sealing issues and keeps fuel system maintenance reliable.
