Holley's new Aluminum V–bowls feature a clear, glass sight window for easy, safe fuel level adjustments. They also include all necessary gaskets and fuel bowl screws for a quick installation.
The best part is replacing your old Zinc fuel bowls with the Aluminum versions will save you over 1.2lb of weight on top of your engine.
