Volkswagen: vaccum line diagram, volkswagen service, vw bus

Question
I just purchased a 1973 VW bus with the 1700 engine.I use the Bentley Official Service Manual that came with the bus.  There are some vaccum lines missing.  The ones to the air cleaner for cold weather heating and I see couple of other blocked off.  I would like to know where to get a vaccum diagram so that I can but the original lines back on.  Bentley does not even list the vaccum line locations and there is nothing on in the engine compartment that showes them

Answer
Hi Dave,

I understand your frustration with the diagrams.

Here is the book that has it:

OFFICIAL VOLKSWAGEN SERVICE MANUAL

PUBLISHER: VW OF AMERICA

(Hunt it down on e-bay)

Also, here are some resources that may even have it on line:

www.type2.com

www.westfalia.org   
(sign up for the user's group -- they have a ton of diagrams)

This will get you rolling!
