No Brake Fluid


so i'm gonna have to replace the whole line and try to remove it but tried the right size wrench and im not able to fit a vice grip in the spot provided..so im out of thoughts for now? Any advice would be appreciated because Im still thinking of replacing the master cylinder and have to bench bleed it but the line is an issue what did i do wrong?One thing i'm starting to realize its not always the big stuff that gives you the problems but the little things as well.
