Holley 4 Barrel Secondary Diaphragm AP236

Please be sure to compare the measurement of the stem. There are several different diaphragms and the difference is the length of the stem. Diaphragms tend to get brittle & stiff over time. Be sure to replace at rebuild time. Cracks & leaks will cause erratic secondary action.
