"Vacuum Resovior" Leak

[cornemuse]

I've been having sporadic vacuum issues for a year or so. Finally reached the point that if I let the car idle for 30 seconds or more, it did not have enough vacuum to shut off. ('83 300 CD turbo). I have found & fixed quite a few problems up to now. Finally traced things to the vacuum res. connection. I thought I was going to break something trying to pull the vacuum line out of the rez. I plugged the line to the res, and then even w/o the res, the system held a vac. on the (mightyvac) gauge for 20 minutes before vac started dropping. As the res is plastic, the 'plug' going in the res is rubber, and the line/tube is plastic, would a new plug really resolve the issue? Once I removed the vac tube, it then slid in with I think way too much ease, slid right in.

I have removed to the garage the res & have siliconed (I mean really slathered on the goo!) a long piece of vac tube into the plug into the res. I will put a loop of vav tube behind the trunk carpeting to the existing vac line to the res. Is this going to work? I junked out a 300 D & noticed the same tube to res had silicone slathered around on it also, is this a reoccuring (or recuring) issue here?

I let the silicone cure overnight, puttin' it back togethrer today.
