Funny how I can spend a years' worth of time over the last 16 years under the hood of my '72, and not notice the different line diameters.....
the top one from the comp is larger then the one on the bottom going into the drier then on to the expansion valve......interesting....
the one going to the evap.....is about same as the one on top of the condensor above, but obviously much larger into the POA valve and return line to the compressor....
I knew the GAS lines were larger, well DUH...but never knew any size differential on the pressure side of things.....condenser....
:crap:
