:huh: Ok I just noticed I had a hose that I had not hooked up......I cant find where! I feel like an idiot but what is this hose for? (351c 4v, 1972)

Heat riser vacuum motor is on that side.

Is your bimetal vacuum switch hooked up underneath the air cleaner base?

I dont know what other emissions your car has, if that line is hooked up at the manifold vacuum tree then your causing a vacuum leak.

Pull the air cleaner off and see what you have hooked up

Check to see if it is pulling a vacuum. First when cold then hot.

That's got my vote to look at first.
