Does anyone have or know where to find a diagram (or diagrams) of the whole vacuum system in a 1982 300D? I've got a couple different emission systems diagrams, but I'm trying to run through the whole system to check for leaks so I need to know where allll the little hoses full of nothing are.

The Performance Products paper catalog might help.. many good line drawings of expanded systems...

That's just the EGR system diagram, SD Blue.

I provided you with a link to the entire service manual.

There is also a condensed sticky list:

A good AND complete one doesn't exist, as was discussed in a recent thread. The colors are wrong on the door locks one that's floating around, and the FSM ones don't mention colors at all. I really should have done one before I redid my lines (totally non-stock now, so no help).

The door lock diagram that Rog mentioned is actually pretty good if you reverse the color legend for lock and unlock and the location of the driver's door vacuum check valve. There is also another diagram posted here that covers the climate control vacuum system.

This helped me get my shifting sorted, and plug things I didn't need

I think this one was for plugging off the egr system. (These are just 1985 diagrams, I sure yours is a little different)

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

The diagram that Charlie is referencing is the one where the red/green stripe legend should be reversed.

That's the one with the swapped colors...

And a bunch of copies of the one with swapped colors...

I'd be willing to draw one that's complete and with all the right colors and labels if we could collect some good info together. My door lock system is stock, so that part will be no problem.
