But heres the realy clincher...the T on top of the VCV is connected to absolutely nothing....I cannot find any lines going to the T. Can anyone share a picture of a proper vac line setup for a 300TD (circa 1983) with this forum please?
Thanks!

OK, 15" and holding is fine.
Now, on the top of the VCV is a T. One end of the T goes to the transmission. The opposite end of the T goes to the vacuum pump. The bull of the T goes to the top of the VCV (with green damper attached).
What I want you to do is to remove the vacuum supply line at the T and connect up your Mityvac (other two legs of the T are properly connected as detailed above).
Pump up the Mityvac and get a reading with the throttle fully closed. Report back with result.
With Mityvac fully pumped up, gradually open the throttle and observe the gauge. It should slowly move toward zero as the throttle is fully opened.
Report back with results.
