Nice original 1980 Flareside and a random question

Rembrant
Came across this truck in my morning coast to coast "coffee searches".

$8000 CDN, or about $6200 USD. Nice little truck, and clean looking.

https://www.kijiji.ca/v-classic-cars/tricities-pitt-maple/1980-ford-f100-flareside-pickup/1356319048?enableSearchNavigationFlag=true

My random question is: What are the vacuum lines on the firewall for? Next to the heater box, just below the hood. Just curious, as my 1984 does not have these, and I've seen them on a few trucks online.
1994 F150 4x2 Flareside. 5.0 w/MAF, 4R70W, stock.
1984 F150 4X2 Flareside. Mild 302 w/ 5spd. Sold.
1980 F150 4X4 Flareside. 300i6 w/ 5spd. Sold in 2021.
1980 F100 4X2 Flareside. 351w/2bbl w/NP435. Sold in 1995

That's a really sharp truck, and if I was looking for one I'd jump at that price.  You can't create a truck like that for twice the cost.

As for the vacuum lines, all is explained here: Underhood/Vacuum Systems.

That IS a nice little truck, and I thought the price was OK as well.

I did check your tech section for info on the vacuum lines before I asked, and I didn't see that page. In fact, when I go back and look, I still can't find it in the contents, only through your link above.

When I go to "underhood", and then "Vacuum Systems", I only have two choices...vacuum diagrams, or vacuum reservoirs.

In any case, I see that the vacuum manifold is for the Auto trans, and something in the HVAC if equipped...some requirement of the Air Conditioning system I presume? Since my truck has neither AC or an auto trans, then I guess that's why I do not have said manifold. Thanks Gary.

The problem is the way I have those pages set up.  Wonky.  You can actually click on Vacuum Systems itself.  The first click gets you a drop-down with Vacuum Diagrams and Vacuum Reservoirs, but if you click Vacuum Systems itself again you'll go to the page in the link.  Not intuitive to the casual observer.  

Vacuum is used on the C6 to give the tranny an idea of how much throttle you are giving the engine and, therefore, how quickly it needs to shift.  Little throttle means the engine won't run away during the shift, but lots of throttle means that if the shift isn't quick the clutch coming in may pay the price.

As for the HVAC system, the factory-installed systems with A/C use vacuum for everything but temp control.  There are vacuum motors under the dash and one on the firewall that move the various doors to change from floor to defrost to panel, and to close the Recirculate door to only use inside air.

That's the vacuum tree, handles any vacuum operated stull under the dash and distributes vaccum to "under hood parts"

Well ain't that slick...I was obviously missing that little 2-click step. Thank you sir.
