Cleaned up the grommet holes for the A/C hoses that still had burrs from drilling, and got the grommets installed. I used RTV in a few places to keep the grommets from moving as some had a little slop. Ran the hoses from the firewall back to the high and low pressure valves mounted on the tailcone skin. I will put a support in for the long run across the baggage area as the hoses droop there.
