Vacuum line diagram needed

Unfortunately, there is not much info in the manual of this vehicle online. We have access to online manuals and these per internet vehicles don't have a lot of info on them.

So, I will attach the info that we have but it is not a complete system diagram as you are looking for.

However, please see the info attached from the online manual that we do have.

If you piece this together, it will give some detail as the thermal vacuum valve has a vacuum line from the carb and it leaves and goes to the EGR along with the transmission diagrams it will give most.

If you need some help finding the leak after you get this all attached, here is a guide that will help:
