Description
Ford Autolite 4100 Vacuum Secondary Diaphragm goes on the rear side of a 4100 style carburetor. There are 2 different styles of this diaphragm, one has a tab with a hole in for the linkage to go through. The other style has a tab with a pin to go through a hole in the linkage. Remove the vacuum cover on your carburetor to ensure which style you need and then select either “hole” or “pin” from the drop down menu.
