Yes, but the stick seal rubber goes quite a way down the tube, so you'd have to put the tee low. Seems easier to cut the turbo return, use a copper plumbing tee of that hose size, then use solder bushings to reduce the diameter of the branch run to use a nipple for the seperator liquid return. I did the same thing after I put the stinkin' motor in the truck with the old, non turbo steel water bypass line, the one without the fitting for the turbo water return, and you can't pull that line with the motor in the truck. I teed into the lower radiator hose.
