Brake line recall instructions?

Seems like there's not much info available on replacing the hard metal brake lines around the gas tank that are notorious for rusting out on our cars. Managed to replace the one going side to side in the rear around the gas tank, but just with my luck the one adjacent to it leaking all across the passenger side is leaking as well. Any walk throughs/ directions on this? Mainly stumped on maneuvering the line out and new one in without bending it. Have everything on the interior passenger's side stripped except the cabin airbox assembly, not sure if that needs to come out or how? Any help is much appreciated.

I’m actually at the dealer for my break lines corroding near the gas tank. SOA said they would cover $2000 out of the $3800 to replace. I had service recall taken care of in 2014, which to me is just putting a band aid on the problem. Needless to say I’m fighting it and awaiting a supervisor to get back to me tonight .
