Help Identifying
R12? Good luck! $$$ Just try cheap propane to find the leaks.....you may stick with it. Fill it with the camp bottle inverted to get a liquid fill. I made a filler with an old screw on torch head that had a valve on it and some AC rated manifold hose. Attach it to your guage set and let her rip. 55 psi on an 85F day. The pump on the ground is a salvaged fridge compressor that I use the inlet for the vacuum source. Start off slow until the clutch kicks in then add to pressure. Hillbilly! :usflag:
