Rebuild a worn SU carburetor and restore proper fuel metering with the Walker Products Carburetor Repair Kit 15578B. This kit is designed for SU 1 BBL carburetors in models HIF, HIF-6, HS-2, HS-4, and HS-6, and serves as a direct-fit rebuild kit for a wide range of listed applications, including the 1972-1973 Triumph GT6, 1963-1974 MG MGB, 1962-1974 MG Midget, and 1968-1971 Volvo 142 — see the Buyer's Guide tab for the full list of 131 applications.
- OE-matched contents: gaskets, seals, and parts sized to support proper fuel metering and fit during the rebuild.
- Ethanol-ready: engineered for use with today's fuel blends, including ethanol-containing fuels.
- Rebuild components: includes the wear parts needed to service the carburetor to help restore fuel flow, throttle response, and idle stability.
- Quality standard: components built to meet or exceed original equipment specifications.
Over time, gaskets, seals, jets, and needles degrade, which can lead to rough idle, hard starting, fuel leaks, or poor fuel economy. If a worn carburetor is the cause of those symptoms, installing this kit replaces the critical wear components as part of a complete rebuild. Confirm the correct SU carburetor model for your vehicle before ordering.
