I replaced the compressor and the accumulator and I have read that you should replace the orfice tube. Exactly where is it located?

Yes, you do need to replace it because it also has a filter attached to it that gets clogged...not to mention the fact that they're cheap. As far as location, I believe it to be just about a foot down from the evaporator, inside the line, between the condenser and evaporator? I will check on that. But I'm pretty sure thats accurate info.
