Maybe I should have replaced the hoses, but I didn't. Hoses appear sound and I did leak test extensively before starting the rebuild. I did replace the compressor, condenser (found leaks at 2 of the U section joints), and expansion valve. I did drill out the old expansion valve and used it for flushing.

I did "borrow" the Autozone vacuum pump again and re-vacuum yesterday before charging with the R12.
