Hi Dave, That's exactly what I plan to replace eventually! As well as the compressor, orifice valve, and dryer. Does anyone know what the target pressures should be if the system is 'properly' charged with R134a? I don't want to overfill it. Also, my guage set reads R134a, R22, and R410 or something like that. There are three extra bands on the outside of the gauges, one for each refrigerant. Depending on the band you read, they are incremented and say "+15......+20......+25....." etc. If I am reading the R134a scale, and the needle points to, say, 30 PSI and +25, what does that mean? The label on the bands say degF. The instructions don't explain this. Thanks!

Has anyone ever seen a car with stock hoses hold R134 more than a year or two? Short of replacing all 3 hoses with modern barrier line, I'm not sure you can get it to hold. The R134 seems to go right through the hoses.
