I have purchased a '90 F150. The engine and front sheet metal were off of it.

I have since replaced the sheet metal however I have to install the vacuum lines for the heater control. I understand that there was a vacuum can in the system somewhere.

Is there a diagram available that shows the engine compartment vacuum line routing for the heater control and the vacuum can?

Thank You

 

Here is the diagram:

Thank You Subford the diagram is very helpful.

I noticed the top left section of the diagram had

"from vacuum distribution on Page 140-1 & 140-2".

I assume this is from the intake manifold?

Thanks again.

 

Yes the intake manifold vacuum fitting.

 

Thank you again subford, you have been very helpful.
