Yeah, I have never even had an air compressor. I'm an unfrozen caveman mechanic from the neolithic era. So I decided to go to Harbor Freight and get a small compressor to power up the purge contraption. Worked amazingly well although the coolant intake hose had a filter on the end that was too large to fit into an anti-freeze jug! DOH! So I dumped the four gallons that I had drained from the car, into a big bucket and clamped a vice grip on the end of the filter to weight it down to the bottom, and it worked out fine.
All that is left is getting the A/C system recharged. It was a little low anyway after 31 years.
