I am posting this for Teddy since he can't remember his password:
So yeah was working on the car last night and accidentally broke an a/c line.
System was full so spent 20 minutes waiting for all pressurized freon to stop hissing.
Anyone have any experience replacing this particular line. It's the small a/c line that runs alongside the reinforcement bar that sits inside the engine. I cracked it near where the main radiator hose is.
Here are some pics.
I highlisted the broken a/c line in yellow

I would not suggest JB weld to hold that line, your looking at pressures in the 250 psi range through that line (also known as the high side line) Just replacing the line will not be all that needs replaced, you are going to need a new receiver/drier from Mazda as well for the system to operate at peak efficiency. The reason is that when the system is opened like that moisture is allowed to penetrate into the system, the reciever dryer is there to remove small amounts of moisture that may be trapped in the system over time, but not atmospheric moisture. After replacing the 2 components the system will have to be vacuumed down, oil will have to be added, and the system checked for leaks before you put freon back in.

Old line is out and replacement line is in.
When I removed the old line I didn't notice any o-rings???
Should I use some sort of thread sealer like teflon tape on the threads before I tighten everything down?

If you didnt notice any o-rings then they are either still in the fittings or on the floor. I just removed all my A/C lines and i know there were o-rings for the condensor and dryer, and if I memory serves me correct ALL A/C systems require o-rings at every fitting due to such rapid expansion / contraction.
