Hi
Daltonultra, it seems that you are really into it, thanks for the tips
The last compressor cames from the opel omega, so it's GM part. The first and the last compressor are the same things, just in different conditions and angle of view (probably )
I dont know from which year that compressor cames from, I bet it's about 2000s. I bought this one becacuse of the price (32 $ + 8$ package). Good quality tyre compressor usually cost more
I have also to make a strong power supply, but it shouldnt be a big problem
