Presure switch issues

[TURKEY131]

While driving my M931 yesterday I noticed a drop in air pressure and could hear air leaking. I located the culprit (MFR-61782 19207-12375453). It looks like it blew apart. Would does this switch for? Any ideas on where to get a replacement?

From the parts manual, it looks like the low air pressure warning switch.

The Memphis or one of the larger surplus vendors. Erik's show to have them.

Just google the part number. They are even listed on SS.

I googled 12375453 as that is the part number. The rest isn't needed.

There is also a check valve at the end of each tank. Make sure it is not frozen up. Some have reported issues with water in the system due to the tanks not being drained regularly and the the check valves rusting/crudding up especially since you are in the land of cold and freezing temps.

The check valve is a midland kn23000 available at NAPA or your favorite hd:

This is the new style switch. You can disconnect the switch and use a piece of wire to short across the connectors on the truck that go to the switch or you can meter the switch with 85 or so psi in the tank and see if its closed to test it.
