2001 Honda Accord roof drain notes

The clear tubing that was installed at the factory has shrunk over time. I dropped the headliner and added a few inches of black hose from NAPA auto parts. The bottom of the tube where they plug in are inaccessible in the front so adding the piece to the top is required. I used a heat gun to help install the new hard plastic hose. Where the hose was not tight in the rear I added silicone to help seal the connections.
The tubing is black hard plastic. It is used for truck air lines. the od is 13mm id is 10mm.
