Location of Vacuum Tank

[84BuickGNYorkPA]

Hi Guys,

Trying to locate the vacuum tank, I can't seem to find it, the vacuum line from the drivers side valve cover goes to it but it disapears in front of the fire wall on the passengers side.
How to I access the tank, redoing my vacuum lines and the control selector on the heater/ac only works on Defrost....

Thanks,
Chuck

Don't think there is a tank. Only plastic feed line.

It's located under the car just in front of the driver's side front wheel. it's a black plastic ball about the size of a large grapefruit. I was replacing vacuum lines a couple months ago and had some knock after replacing them and adding a powerplate. A couple days later I realized I had fed the vac line down through the fender but I forgot to crawl under the car to connect to the vacuum ball.

My 84GN has a 2nd vacuum tank located on top of passenger side fenderwell.
