I have a new theory: the fan clutch could be faulty, causing higher pressures than optimal, caused the first pinhole. After the initial hose replacement the AC ran fine for 350 miles - but highway miles. When it leaked after that, Mrs. Cusser was driving it around the arena at very slow speed, not enough to ram air over the condenser. So my theory is that the high pressure kept building up, and thus had to "find a place to leak out" eventually.

After start up, one can readily see that the fan blade is spinning slower than it should, and the blade failed the "rolled up newspaper stoppage test". It is a lifetime warranty fan clutch, and should be easy to replace using the special extra-long 10mm wrench I invented.

Anyway: fan clutch is bad, and I always say "fix first what you KNOW is bad".
