The carburetor on my 1983 Ford Ranger is the dirty carburetor with the unknown vacuum outlet next to the idle mixture screw. The tag number is
E37E ABA.

The other carburetor is E37E AEA without the unknown vacuum outlet. The seller claimed it came off a 1985 Ranger. I've already tried this carburetor on the truck and it seems to work fine. However, I now have a vaccum line disconnected.

Any idea what this outlet does?

Has something to do with emissions I assume. Does your state do emissions testing and or inspections? If Not I say plug the vaccum line and see how well she runs from there. If the truck runs, drives good without it hooked up them I would leave it as such.

The line on my truck is located on the top left of the diagram on the VAC SW. The actual line is the black third one down and it attaches to the SP on the carburetor.

I've also attached a 1985 vacuum diagram for the comparison on which I have a 1985 carburetor.

Could the vacuum line be attached to something else?

heck to see if it even gets any vacuum when the engine is running if so it is ported vacuum for I believe it is called altitude compensator or some goofy vacuum switch. My old 2150a feedback carb had it on it but it was blocked internally if you cant blow through it its useless if you get ported vacuum when you open the throttle it can be plugged or used for vacuum advance.

I just ran out to look at the carb off my '85, it has the same hole. I can't see any threads inside the thing to put a nipple on but there is a fair amount of sand in mine from when I sandblasted/painted it.

It is too tiny to really do much with for a vacuum source, mine never had anything in it since I have had it. I notice there are also a couple similar holes on the top side of that flange as well.

I didn't even know the hole existed before this. :D

All I know for sure is that my '85 doesn't have that line.
I would pull the codes and see what comes up and start there.

A carb (or any part) that 'will work" may not work right, especially if you have to pass smog.

I bought a computer from someone on this list that said it ran great but he just wanted to DuraSpark his truck. That computer was junk and barely ran: some people say anything to get a buck.

I have the same carb on my Ranger with the same outlet. The E373 ABA carb is what I believe to be a California Emissions carb. I also think it is 1983 only. Right now I can't remember what the vacuum line goes to. I have vacuum diagram for my pickup and could trace it down for you. If your truck isn't from California, you will not likely find a line to hook up to the port. Wanna sell that carb? I would like to have a fresh Cali-Carb on the shelf for the little red wagon.
