This vacuum layout should clear up any further issues around where the pipes go. I have checked my vacuum hoses against it and it is correct.
(F_D, I saved it as a pdf and it fits a A4 page so you may want to scale it down. Let me know if you need help or want anything changed)
Have fun

EDIT by F_D: I have added a smaller version of Scooter's sketch, click on the PDF file for a full-size version.
