well after getting my A/C all hooked back up and sucked down we decided to charge it and try it/ Will filled her up and it got down to 50* inside (when it was 90* outside) and then it went BOOM and blew up a hose. All was good but Im confused, the lines going from the condensor to the evaporator are the high side lines? Cause thats what the gauges were reading. and the big one going from the compressor to the evaporator (POA) is the low side?
I thought it was the other way around but thats how it turned out. I thought the high side hose connection (larger fitting) was on the POA valve and the Low side connection (smaller Fitting) was on the liquid hose from the dryer to the expansion valve.

Any Help? Is it right? It was working pretty good but the line that runs infront of the condensor from it to the dryer blew up guess Ill have to get a new one made.

The High side starts at the compressor, then goes to the condenser, through the receiver/drier, then to the expansion valve. The Low side starts at the other side of the expansion valve, through the evaporator, through the POA and back to the compressor. The port on the liquid line (condenser to TXV) is the HIGH side port. Be careful if you are using small cans. If you open this port to the refrigerant can it WILL EXPLODE if there is a charge in the system!!

The line that blew was all metal, correct? Old Air Products should stock it.

Alright thank you thats what I needed to know. Yes the line that blew was the metal one, Do you think I could have one made locally? Does it have to be a metal line?

IIRC, that line is about $12. If you have one made with rubber, it will probably be about $35-40. Check with your local NAPA store and see if they make hoses. You won't be able to get an all metal line made locally.
