Coolant bottle overflow reroute

I made this to raise the bottle overflow above the water line.  This was simple, I used a brass 1/4" x 1/4" npt and drilled it into the bottle cap.  I then used 1/4" I.D. tubing and ran it up to the hood.  At the hood end I used a 1/4" x 3/8" npt plastic fitting and stuffed it with fiberglass screen to keep bugs and dirt out, but not enough to block the airflow.  Added a little RTV to keep the plastic fitting in the tube and around the screen to keep it in place.
