For 1 thing Im missing the vacume canister.Can plug that line off so that I can at least get this thing to run?As for the other number I`ll get them Saturday when it warms up.Theillustrations are of great help except the only difference is that my 3 connector is round not rectangle.That doesn't matter probably it just a drawing correct?
Also I need to know to size of the vacume line and how much to buy.A shop is going to do the work for me.

 

The reservoir helps the vacuum system to maintain the actuators in the selected position, if there is a slight vacuum leak in the system. In a pinch you can cap it off.

The drawing is for illustration purposes only, (I'm obviously not an artist )

 

Are all the vacuum lines the same size? Becuz of my 4wd issues, that's another thing on my list of things to do....

 

Nevermind Sorry chuck I didn't look at your diagram with my eyes open thanks for the info I appreciate it.

 

Vacuum lines are 5/32" & 7/32". They won't fit on the wrong way, so you can't screw it up

 

I was able to buy the 5/32 line but our stores are out of 7/32 so I have to wait till they get more in stock.With storm on the way I will have to wait till probably Tuesday.

 

Would this be the same diagram for 1999 trailblazer???

Figaroman1, only if you have the 3 button, NV233, 2 speed selectable transfer case. The 4 button, NV236, Auto 4WD does not have a vacuum switch on the transfer case.

 

I`m so happy I got rid of the vac actuator setup. Alot of snow in the northeast and been using 4 wheel drive every other day. Hasnt failed me yet

 

Guys question on the vacume lines on the engine can I use the same size line instead of all different sizes?
