I accidentally knocked this off (line F) while doing a service. It is coming from E (from the Bentley manual this appears to be labeled as vacuum control for auxiliary vent). The hose appears to go to a vacuum switching valve I am not sure where to find it. Anyone know?

Had to figure this out recently - I believe this is the right diagram - PET illustration 107-00 model 87-89 - connects to back of throttle body. system pulls heat from oil tank to keep throttle from icing. only operates at certain temp

Thanks! I found a better diagram as well. Goes to 13. First valve adjustment in the books. No issues except for this hose mystery.
