Heloo again everyone, while i know a lot about A/C systems in these car's i do have a question, has anyone been able to find just the R134A filler valve connection, see on my 1990 i have the factory filler pipe but its fitted with a R12 filler, i dont need a Acc and have already drained and refilled the compressor, replaced most of the seals, but cannot fill it, the only place i have been able to find this is in the Volvo Conversion kit and i really dont want to spend $150.00 for just that valve. should i be prepping for a salvage yard run? i could fill the system with a wal mart type kit which fits the Acc low port but would rather fill it as volvo intended. Yes i had already reciewed the FAQ sadly it mainly touches on the pre 90 setup's and in 93 volvo went to 134.
