oh, and do not forget the orifice tube is directional, and they are not usually marked. if you install it backwards the system will not work. ive seen a few guys get there systems all ready to go and either place the tube backwards or completly forget it all together. If you hook up the preasure gauges and theyre level togeher, thats probably your cuase. then you have to suck the whole system back, fix it, and recharge again. its not worth the time, so check that you have it right the first time.

assuming your starting from scratch. if you didnt remove anything sept for the compressor, then all you would need is the conversion kit and new o-rings.
