Helloooooo Everyone

I was trying to replace one of the AC lines today and couldn't get the bugger to come off. Found out I needed a special disconnect tool, so I called up Autozone and asked, they said they have some so I went and bought it. It looked like it should work but when I got home and repeatedly yanked on the line, no go.

So two part question. Is this the right tool and I'm just a powderpuff, or did Autozone **** up again?



And if it's not the right tool, where can I find one. (tried NAPA and they didn't carry any)

Here's the connection I'm trying to get loose. Scratch marks from the yanking

 

Really trying to get this out. Anyone?

 

that's the right tool..its really simple look it up on youtube its the same on every car to release the line

 

 

Welp I feel like a dumbass. Didn't even think to look on youtube.

Thanks or the help Ja
