This picture is nothing like mine, mine has two large silver lines coming out of the compressor,one witch has a valve with a cap on it and I think the oter goes to the condensor,=. I went to auto zone a little while ago and got one of those kits.hooked it all up and the gauge showed nothing so I done like the directions said and it drained the can.Then I realized the gauge was messed up and thats why it read nothing. So I took it back to auto zone and traded it in on a good gauge, come home hooked it up and it said it was in the danger zone so I drained it till about 55 or 60 lbs still I have no air ,I can jump the switches and it will work. yes I need help!!!
