Is this on your diesel? I didn;t know they had one. Where is it located on the engine?

I haven't really messed with those much, but it appears you can just loosen the retaining bolts then rotate it as needed. However, make sure you have good vacuum before even messing with it.

Jeb, that is the valve that is needed for the C6 vacuum. It is right on the injection pump, sourced by the vacuum pump.
