vaccum leak

Ok, I know I have a vaccum leak. I have manual hubs now and those lines are capped. The AC is blowing through the deforst and the pump is running non stop. I have replaced the vac pump a couple of years ago and it worked fine then. any other places to look?

Is the 4wd switch tied to the vacuum system for the factory hubs?

I had a GM product that had issues with vacuum tubing from a switch to the tranny that I had to trace the lines on.

If your diesel is like the gasser, then it is most likely the vacuum solenoid.
