get a blueprint for the pump so u dont drill into anything bad
I liked your idea before and I was thinking about this a little while back when I saw other compressors with the crankcase port.
A few posts back I mentioned that I wanted to cut open a compressor like mine to see the internal construction. I cannot find a blueprint of the NF9FX with enough detail to perform such a surgery. I would put a line as you mention most likely.
Does what I have here in the drawing at the reservoir going to work as well? Should I chose to go that route!
