This thread has been a life saver! Thank you all for your valuable input! I finished my putting my AC system together today. I've never done any kind of AC work short of buying a can with the hose and filling the system. I replaced the compressor(it seized), accumulator, orifice, and o-rings. I also flushed the whole system and vacuumed it with a vacuum pump and manifold gauges from HF as per recommended in this thread. I'm glad I went the route of buying my own AC tools since now I can do this on any car and save hundreds by not taking it to a shop to do something that was so easy to do. Took the car out for a drive and the AC vent temp dropped to 36 degrees!! I'm good with that!
