Bring a worn Holley four-barrel back to spec with the Walker Products Carburetor Repair Kit 15456B, cataloged for the Holley 4 BBL, Model 4150 carburetor. It's a direct-fit rebuild kit for the 1969 Chevrolet Bel Air, 1969 Chevrolet Biscayne, and 1969 Chevrolet Impala — see the Buyer's Guide tab for full engine-level details.
- Carburetor application: Holley 4 BBL; Model 4150 — matched to that carburetor's rebuild needs.
- OE-matched components: gaskets, seals, jets, and needles built to help maintain proper fuel metering and fit.
- Ethanol-ready: engineered for use with today's fuel blends, including ethanol-containing fuels.
- Rebuild contents: includes the wear components needed to service the carburetor.
Over time a carburetor's gaskets, seals, and metering parts degrade, which can show up as rough idle, hard starting, fuel leaks, or poor fuel economy. If those symptoms trace back to worn carburetor internals, a properly installed Walker kit replaces the critical wear parts to help restore fuel flow, throttle response, and idle behavior. Always diagnose the cause before servicing, and follow the carburetor manufacturer's rebuild procedure. Backed by Walker Products' long experience in fuel-system components.
