I finally decided to break out the soapy water to identify where my air system is losing pressure, and I found two similar connectors that I think are the culprit. It's a slow leak, but I figure I should try to replace the connectors as soon as possible to avoid overworking the compressor. Can anyone identify what these are and where I may be able to get replacements?
One is located on the firewall where an air line connects to the driver seat, and at one point in time, the stop sign (removed and capped off). The other is located at the back of the air tank.
Thanks for any help or suggestions!
