Designed specifically for the iconic 4150 and 4160 series four-barrel carburettors, this “Renew Kit” is the definitive solution for high-performance maintenance and restoration.

Don’t settle for inferior aftermarket gaskets that can shrink or weep petrol. This kit contains only genuine Holley components, ensuring 100% compatibility and a perfect seal. Whether you are prepping your classic American muscle car for the show season or refreshing a drag racer for the track, this kit provides everything needed to rebuild your fuel system with confidence.

Key Features & Benefits:

• Complete Overhaul: Includes high-quality fuel bowl gaskets, metering block gaskets, needle and seat assemblies, and power valves.
