Ok seems like the vac diagram sticky is all but broke,
I did a valve job on my 81 SD this weekend and the vac lines that go in the junction plug on the top of the valve cover made their way out and I have no idea how they go back in. I only found three. is that all there is, bucause under the black box every port has a hose. My car wouldnt shut down today on a few errands so hopefully it is because of these and not some other line I gotta trace down.
