I am going to have someone do it. I tried to plug it in and it was escaping as I was trying to connnect it. Not sure if I know what I am doing with the R12.

I don't know if I just need to be a little quicker on the draw or what. When I did it with and R134 system I just plugged it in and pulled the trigger.

The r12 is in cans and has a hose with a penetrating needle to release the contents of the bottle. I am using a bottle I previously opened.

I am connecting it to the large diameter pipe inside of the engine compartment, not the fitting that protrudes out the front of the car.

Let me know if I you have any suggestions.
