how to replace check valve to selector vacuum line?

I tested this line and is leaking. It is the line that goes from the check valve by the a/c box thing to the "harness" of those six vacuum line connections behing the glove box.

I have no idea how to replace it. Can someon please help me with it?

I have never looked to see exactly where it goes. Are you sure it is not just split on one end? Have you tried to pinpoint the leak? Perhaps you could just splice out the problem with some hose and a hose union.

hey shoebox, I dont know where it is exactly, but i have a feeling it is on the underhood side of the hose. i had a helper hold the hose, but she probably didnt think anything of it if she heard hissing. It is a good size leak, i think may be causing my long time idle surging. i am not too crazy about just splicing it, does anyone else know how to replace this hose?
