I recently removed my vacuum lines for a valve cover replacement and did not make them and some broke. I need a diagram for the vacuum lines please.

Hi,

You have the same kind of luck as I do. LOL As far as the vacuum hoses are concerned, I attached the only vacuum schematic I have below. Take a look through them and let me know if it helps or if you have other questions.

Also, if the schematic doesn't provide something you need, take a pic of the problem area and upload it for me to see, hopefully, I'll recognize it.

Let me know.

Take care,

Joe
