51 degrees F air temp at the left-center vent is well within the performance parameters of the info table that I posted above in #112. Time to leave well enough alone and enjoy your accomplishment. I'd use the A/C throughout the Summer and recheck pressures and temperatures in September.

I am just going to leave things for now. If it keeps putting out cold air thats good enough for now - knock on wood. I am happy to have gotten it fixed for so little - even if for now.
I wish I had properly checked it with the gauges first time around by getting it up to 1500 rpm, now I wonder if they are off. But there likely not off by that much. I just ended up with Harbor Freight tools after my initial go around. I bought the same vacuum pump again, and this one did not mist oil. One of the biggest hurdles on this was tools. I have read a lot more - and everything points to either spend the money on good tools - and that means at minimum mid-level priced stuff from the top brands, because even the cheaper stuff from the good brands have issues. I re-read the reviews on the Mastercool set i had ordered, and every one of the 1* reviews had the same hose issue I did.
O-rings were another bit of a hurdle. I ordered OEM O-rings. One size came in individually sealed marked bags. The other came in a baggy with no label, and they were brown, not black. Z1 assures me they get them from Nissan and the come in a larger overpack. I want to believe them - supply shortage maybe. However I did not use them anyway - I used the O-rings that came in my 4-seasons "all O-rings needed" for my vehicle - because I was still communicating with Z1. I did use the other OEM ones on the suctions tube.
The 4-seasons dryer I bought came with O-rings. Luckily because it appears the 4-seasons kit had nothing close to that size. It does appear the giant set of O-rings I ordered from Jeff Bezos does have the right size. So O-rings could be an issue. After the fact I found the manual does list every size I am supposed to need - but the manual is lacking in other areas so I am not sure I would trust that fully either.
Anyway, if you read this far - thanks again for all your help everyone. I learned a ton, and would encourage others to try on their own also - its much less daunting (with a lot of help) than it seemed at the start.
