That is a vacuum res and not really needed. I think in the stickies there is a vac diagram. Check front actuator on the axle. Is it getting vac? If not no 4wd.

Your 4wd line is a thin red vac line that tee'd from the line going to that ball. You don't need that ball but you NEED vacuum on that red vacuum line so just run a rubber line from that red one to your carb

Give this thread a good read. It's in the "Write-ups and How to's" sticky at the top of the section.
