I found the A/C leak. What I did to do that was to remove the micron gauge and hook the yellow hose up to an air compressor with a fitting that I had to make. I put 90 psi positive pressure on it and I could hear where the leak was.
It was coming from his crimped fitting:



Why this leaked, I have no idea but no other good choice but to build a complete new hose.



The hose and fittings with the leak is #8 reduced. Since I didn't want to order the exact same parts again, I decided to go with the standard hose and fittings this time. This hose doesn't really benefit with the reduced size anyway since it doesn't have to bend much from the compressor to the condenser. Here is the new hose installed:



I do believe it has no leaks now but I ran out of time yesterday to pump it down for as long as I should. This photo that shows 440 microns was a few minutes after I shut the gauge valves and pump down and it did seem to be holding at that. But the owner needed to close up his shop for the day so I will go through this process again allowing for more time for both the vacuuming and watching after shut down. I also want to remove the fan belt so I can turn the compressor by hand to disperse the oil inside some.



The top install isn't complete yet but he's getting there. He says it's kind of a trial and error process to get the wrinkles out in the rear corners and takes a lot of time. He said at this point he needs to get it out in the sun on a hot day and that will allow it to stretch easier for the final adjustments. But we've had mostly cloudy and rainy days for the past week and cooler temperatures. Still rain in the forecast too.
