low pressure a/c line

Just noticed I have a hole on my a/c line, low pressure pipe. A little pinhole leak from my throttle cable bracket rubbing against it. Am I able to just remove the line and get it replaced or do i have to replace the whole thing, with the tank? My other option was to solder the hole shut but im not sure if it will hold under pressure. I just bandaged it with duct tape for now so no air will leak onto my intake manifold, but im definitely not using the a/c til it gets fixed. Doesnt look too simple to replace since im not sure where the line ends when it passes the firewall. Does anyone know how much this part will cost? or if you decided to scrap your a/c in your car and have this line, are you willing to sell it? 02 G 4 banger CA spec if that matters.

i would replace the entire hose. Then have your ac evac and recharged with die... for future issues if any
