      York Compressor is just behind the head lamp. Downstream from the compressor 
      and in order is a coalescing filter to extract oil and moisture from the 
      compressed air. Next is a check valve, followed by pressure activated switch 
      that controls the pump's clutch, an over-pressure safety valve, and the 
      2.5 gallon air reservoir. The reservoir has a pressure gage to monitor air 
      pressure. |
