    Hey all,
    I'm going through and replacing all the vacuum lines and trying to get everything connected up correctly and I can't find this one on the book. It's the line that come from the air cleaner that has me confused. I have a port just forward of the EGR that is capped but it will pull vacuum all the time which will keep the hot air valve pulling hot air from the exhaust manifold all the time and not switching to the "cold" air. Any help will be greatly appreciated. 20221020_171655 (Medium).jpg

    On the other side of those 2 vacuum hoses in your second pic should be a thermal switch that will only activate the hot air flapper on your air cleaner snorkel when it is cold. When it’s hot, the switch won’t let the vacuum get to the flapper vacuum motor.
