Maybe I should be more descriptive.
Currenty, the main vacuum line from the control valve attaches to a
PLASTIC nipple. This plastic nipple has been RTV'd and crammed into
the intake manifold. I would like to replace this plastic nipple with
something that maybe is OEM. Again this is for a dual port setup.
The VW manuals don't show this.

Question: To autostick owners, how is that union on your vehicle
provided?
