Without even looking at your image, I had a pretty good idea of what you were probably referring to.
From the factory there were tubes supplying coolant to the TB to prevent icing up in certain atmospheric conditions. It's a pretty common practice to remove them. There's no harm in leaving those ports open if the tubes have been banished. You can also now remove those brass fittings to make it look a little better.
By the way, if you keep the
file size of images to
2 MB or less, the actual image will appear in your post rather than a link. Like so...
