What about this one??

Well, you guys did so well with my last unknown hose, I figured I would throw another one at y'all.

Let's see if I can explain this w/o confusing everyone.
OK. Well the hose in question is the blue tinted one. It is just there not hooked up to anything. The other end of the hose goes into a small cylindrical canister with two inputs on either side. On the same side as the blue hose, the green hose plugs into it. That hose feeds into a T conection. One side goes to the carb and the other goes to the item on the right of the pic tinted green. On the other side of the canister the red hose comes out and plugs into the red tinted item that appears to sit above or right next to the thermostat housing. The orange hose comes out and plugs into the vacumn advance on the distributor.
When I place my finger over the opening on the blue hose, the engine revs up quite a bit. So anyone know where it is to be pluged into??
