A return line. Starting in 71, the fuel pump had a return line.
It is a pretty good idea to retain this, you can install a high flow pump to ensure that your bowls never dip low in fuel level, but witht eh return line, the fuel pressure will not increase to the point of blowing the needle off its seat.

Where does that hook up to. I only have one inlet and one outlet on my fuel pump. I was thinking maybe this went to the old charcoal canister. I am running my exhaust throught the frame and that is where the fuel lines are spliced together. Instead of using a different fuel line on Blazers the front piece is the same as trucks and there is a second piece going back to the tank. I have to replace the whole thing or relocate the splice
