Vacuum Diagram

I have a 1986 F150 4x4 302 w/AOD transmission. It seems to have a vacuum leak that isn't super obvious to me.

I am looking for a vacuum diagram for this pickup if anyone has one.

Thanks!

Thad

Also, if anyone knows the sizes of the various vacuum hoses that would be great. I don't live in town and want to get the parts on hand so I can get this done without several trips to get parts.

Thanks!

I looked over the lines last night. I didn't put a vacuum gauge on it but I verified functionality of the vent door and brakes both vacuum operated. Not sure if that's any validation of the vacuum system or not?
