If it is the water line you need to plug it. It was for the thermal wax or to preheat the carb. I used a silicon hose and part of a roller bearing to make the plug on my truck.

Yup plug it its only needed for the stock carb.

Both are correct - not needed and can be plugged.

thank you guys! thats what i figured !
