A fairlly common request on this forum is for information on the vacuum lines that help manage mixture and timing in the 380 series engines. A very common bit of advice is to check for leaks and replace connectors as needed.

I have been chasing a warm-up regulator problem in my 380, and had occasion to access the functional diagram. In addition, I received an e-fax from the dealer parts book as we were discussing what pieces to order. So I thought I would post both of them as a ready reference.

If you need a piece, you can call any dealer's parts department, give them the Group and Sub-Group number at the top of the page and it will be easy for you to find the part(s) that you need.

There are minor variations between 1981 and 1985, but these diagrams will get you in the ballpark.
