What is this hard line under the TBI plumbed to the Intake? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What is it? I don't seem to have a comparable place on the GM Vortec Intake for it.

See the blue arrows. Not sure what it is for... I went back outside to look at the part. The hard line run along the length valve cover towards the firewall then turns 90 degrees (horionitally) behind the end of the valve cover, then 90 degrees vertical. Any ideas? I am sure I need to block off or "T" a line if I don't use it on my new intake, so I really need to know what it is.
