I have a 1984 Ford Ranger 4x4 with 2.8L V6, carburetor number E37E-AEA.
The accelerator pump diaphragm is perforated.
Small holes are visible when I hold it up to a light.
Is this part available anywhere?
Is it included in these carb repair kits that I see on a lot of auto parts sites?
The sites don't list the contents of their "kits."

 

any auto parts store will have the part, they might have to order it but it is available.

 

Every kit I have ever used has come with a new accelerator pump diaphragm. (If there was an accelerator pump) If you order a kit, and are concerned, most have a 'box' with a cellophane window you can look through to determine the presence of a diaphragm.
I'd be heading to NAPA or one of the other competitors. Maybe even online, depending on price and expediency. If I can afford to wait a few days more than the parts store delay, it may save some. Most parts stores will have to order the kit from their supplier warehouses, and it should arrive within a couple days if they stock it, longer if it has to come from a distribution point.{which is where Rock and some others get their parts, I think}
