Yeah, that's the tube. It was easy to install but just be sure to line everything up before you tighten it down and you should be fine. You can sort of feel when it's seated on the opposite side (where it connects to the water pump). I didn't have to remove the intake or any of that. You can do it by simply pressing it into the water pump. You'll know it's in there when you try to pull it out and feel resistance. Best of luck with it. Please let me know if I can help with anything else during the procedure. I learned the hard way how to do it right, LOL.
