Hey everyone, today I was working on my car, and I had the air filter box out to replace the vaccum hoses/ connectors that attach to the idle control valve...

I replaced the white connector and hose that attaches to the right of the ICV, but when I looked at the longer hose that attaches to the left side of the ICV, I backed off like a wuss when I saw how deep it was into the manifod and the fact that some device with a line from te fuel distributor attached to the hose at the bottom....

How do I replace this hose the correct and safe way? The hose is pretty stiff so it might be leaking some vacuum, since there is a slight surge when my car is at idle....

Thanks people!
