I got this 86 corvette cast iron heads. There is a vacuum hose coming from the purge canister. It come up the driver side wheel well can anyone let me know what this plugs to?? I know one goes to the fuel tank but don't know where the other one goes..
No. Late 86's switched over to aluminum to reduce weight. Look on top of your radiator. Should have a similar diagram. They all come out of the compartment where the headlight is. There's a round canister and a valve/solenoid. From drivers side, one runs across front of engine and goes under the throttle body. Another leads up to the the throttle body but splits in two(that's that y shaped tube). One end goes to the egr solenoid, the other goes under the plenum. The one that runs to the fuel tank has a t fitting that branches off and goes to the cruise control module...I think. Don't quote me. Some of those lines are plastic. Would advise replacing them with rubber.

The one that goes to cruise(splitter) is from the vacume ball, the line from canister goes to the tank, beware they pressure tested my whole system for leaks at my smog test. I passed!
Cliff that is the same diagram that I have on my car, wasn't sure how it was suppose to hook up, do have a picture of the aluminum pipe hooked up? When I purchased the vehicle it did not have that pipe. I am wondering what it is called so I can located and purchase it, sounds like I will need this
That pipe is well hidden by the fuel injector harness on the left side of the engine. In the second pic I will post (upside down, damn phone)you can see the hose curve around the valve cover. In the first you can see the end where the pipe connects to the fuel rail

It connects to the intake manifold above the cold start injector:
I had a picture of a bare intake manifold with just that pipe in place but I can't find it.
There were slight variations on this pipe. Some do not have the vacuum hose connection of the left hand end. I have seen later cars that just have a rubber vacuum hose instead of the pipe.
Can someone help me!
