You may want to connect that to your header tank, and use it also as a bleed valve. If you are referring to the tap that is on top of the engine, toward the bell housing end, I started out with the header tank at that location. I couldn't get any air to bleed out at that point. Moving it to the side of the thermostat housing was better, but still can't get it all out. Also bleed the air and water off the top of the header tank (suitable cap) to an expansion/overflow tank just like on the car. That is exactly what I have.
