What is This??

I've searched the web and looked in every Jeep book I have - I can't identify this tube/valve? thingy.
Background; 1985 CJ7, 258, Holley ProJection 1D - other than the catalytic converter, this CJ has relatively little for smog/emissions. No air pump, no air fittings into the exhaust manifold, etc. I'm underneath replacing u-joints and I see this tube, maybe 3/4" diameter, running from my head pipe just below the manifold, down and across the bottom of the bellhousing, and then running up to a valve (I think) on the passenger side of the motor. The tube continues upward and runs through the firewall. I can't see where it comes out in the passenger compartment.
I have no emissions requirement where I live, and I'm for simplifying things. If I don't need this and it doesn't through a wrench into things, I'm for removing it. But I can't seem to find what it is.
