Vacuum Secondary Metering Plate Back Up Plate Fits: Holley Carburetor

This thin steel separator plate along with the matching gasket helps to achieve complete gasket sealing of the secondary metering plate eliminating lost signal and poor performance in the secondary fuel circuit. This setup was used from the factory until the late 1990's and then stopped using it to save money. Newer carburetors without this plate experience swollen gasket material in the fuel slots of the secondary metering plate causing poor performance. Don't risk reusing your old bent and corroded plate, or worse yet not having one at all.  Also fits Avenger, Street Avenger and other similar carburetors.
