Default Retrofitting 1991 cherokee a/c

I just bough 134 a/c kit to retrofit my 1991 cherokee. When I started to recharge the psi went to 100 psi instantly. All other freon was evacuated. And the fittings were installed correctly. But it just isnt entering the line for some reason. Do i need different kind of connectors. These came with the kit.

You have to charge with the can upside down so liquid goes into the line. It is a blend and the lighter stuff boils off first and cools the rest and then the vapor won't go into the system.
