Thanks tmoore4512 and the rest! I will be getting the R134a drier then. Does anyone have any info on that particular O-Ring on the early high pressure hose fittings at the condenser? It does look like a special one and I have not heard anything from the dealer. They still haven't got the O-Ring so nobody can tell me anything about the diameter or type of it. I heard if you take stuff apart and mess with the O-Rings its better to use the "green" ones to replace the "black" ones. Yes, the EPA sucks, and as for Al Gore, he has a new inconvenient truth.
