You need to repair both tubes, they should both be getting engine manifold vacuum, the canister and the line that leads into the interior of the truck, via through the firewall withthe main PCM wiring harness.
Ok, I respliced the hose and secured it with a heavy duty shrink tube, and it appeared to be a vacuum tube for the normal - max a/c problem, I was having. I have that all fixed.
