The Stovebolt Site Forums The Shop Area General Truck Talk Vacuum hose fitting on 216 Manifold

Could someone please tell me the easiest way to either Remove OR Plug the wiper hose vacuum fitting on the manifold for my 216?

It doesn't seem to want to come out, and the hex part on the top of the fitting doesn't seem to be a normal sized wrench size.

I recently switched to electric wipers, and the vacuum leak doesn't make things work very well (or at all). :mad:

Thanks in advance.
