I'm doing some a/c work on the car because I bought it with no compressor and I will be flushing it putting new o rings in the system and a new accumulator. I can't for the life of me find the old orifice tube I checked the low line going to the accumulator and I just put a condenser in 2 days ago because a line was broke at the condenser and still no orifice tube. so please some one tell me were it is.
