as much as I'd like to sell another MicroLevel, my suggestion would be to call Jim K at Applied GMC.
Get 2 new compressors as the second one is probably worse than you think it is.
Jim will be able to set you up with as much of a 'Kit' as you could hope for AND would be able to do tech support.
If you live in California near freemont they can even do the work for you.
Or Jim Bounds at the GMC coop can do it too

I really appreciate the prompt and detailed guidance.
However, I tend toward Jim's suggestion. I have had a devil of a time
finding the necessary skills to diagnose and replace my system . . . at
home, with no deadline, and no rain. I can't imagine the hassle of dealing
with it out in the desert or rainy woods.
I would much prefer a new system that I need not worry about for another 40
years.
Regards,
Jay
