Thanks for the info. I'm building a Frankenstein Air
compressor. The engine, compressor and tank all came
from different compressors. I have an unloader valve
that vents to an outlet when the compressor reaches a
certain pressure, and it also has a safety pop off
valve. If I can figure out the unloader valves on the
heads, I may not need my unloader valve then. I need
to figure out how the "fitting" or whatever it is on
the back of the compressor works. This compressor is
probably pretty old, so I don't know if I can find any
manuals on it.
Thanks
Mark
