I did a very bad job describing what I wanted to do. For that I’m sorry. Think my old age is playing with my brain....
You are correct. The Offy vacuum goes to distributor. I wanted to know to run vacuum test, do I have to T this connection. Or can I disconnect the distributor and use the line strictly for the vacuum gauge.
Again thanks for your patience.
