How can I get replacements for the tiny o-rings in the pressure sensor?
Our compressor literally blew apart (the compressor stage, not the tank) and sent oil down the air line, which gummed up the regulator and caused it to leak. I had no trouble cleaning everything and getting it back together except for one tiny oval o-ring under the block that connects to the pressure sensor on the board. O-rings bounce! Wilkerson lists some replacement kits for this unit, but I haven't been able to find them, or even what parts are included.
