So my dad's cruiser just built a pin hole in the rear HP AC line. I've tried using some A/C couplers to fix it. But it's right at a bend where the couplers can't seal. So we're gonna have to replace the entire line. So now I'm thinking about just trying to plug up the rear AC as a temporary fix until he gets the funds and I get the time to fix it for him since I've heard that's it's a nightmare to replace. Any clue if this would be viable option and if so how much A/C refrigerant would it take. I'm guessing probably close to 1/2 a pound less.
