You must replace it . Remove the 2 screewes that hold it to the distributor base and it will then slide out and the 90 degree rod will drop out of the bass plate hole as you are moving it. Then put the new 1 on and hook the vacuum hose to it.

It won't. That vacuum line tells the distributor When to advance the timing. There isn't enough vacuum loss to stall an engine.
I really depends on what distributor you have on the engine. It could be a mechanical advance distributor or a vacuum advance distributor (stock). Google "the Somba" Volkswagen forum and all will be explained.
>you don't adjust the vaccuum advance. you adjust the distributor. then when engine is running the vaccuum advance will work automatically to the needs of the engine< As a matter of fact, the Ford vacuum advance is easily adjustable. Put a 1/8" Allen wrench through the open of the vacuum advance canister where the vacuum hose goes. Screw it in to slow the rate of advance and screw it out to speed it up. I think it works on a spring preload system.

Manifold vacuum usually. There may be some instances where someone reworked a distributor to arrive at a specific timing curve under load using ported vacuum with the vacuum advance, but this would be rare as most people would re-curve their distributor by changing advance weights and springs and would limit the advance built into a distributor so they could use more initial timing without having the total timing go over 36-40 degrees when the engine is revved up and all advance is in.
The distributor is off a tooth or two. You can pull the distributor out and turn the rotor a little and put it back in. Then re-time the engine.
There should be a vacuum source on the carb above the throttle body that gives spark ported vacuum. You can connect a tube from this source to the distributor.
If you're talking about the vacuum advance for the 216/235 distributor, then yes it has the vacuum advance, which runs off a carburetor connection close to the idle adjustment screw.
Remove the distributor cap. Remove the hose to the vacuum advance. Remove the two screws holding the vacuum advance on. Install in reverse order.
pull the hose off the vacuum advance and some of them have a set screw inside the hole.
