Appendix II - Changing Faceplate / Bezel
The Wideband Failsafe gauge comes with the black bezel and Air/Fuel-Gasoline faceplate installed.
However, a silver bezel and multiple faceplates are also included. To change them, orient the gauge so
you are looking at the faceplate. Rotate the bezel counter-clockwise to unscrew it from the gauge cup.
The bezel, lens, and rubber spacer are all removable. Next, remove the faceplate, but note the two
keyways on each side. When inserting the new faceplate be cognizant of these keyways and line them up
before reassembling.
When reassembling the gauge, it may be necessary to apply a light amount of pressure on the lens and
spacer to keep the faceplate from rotating when reinstalling the bezel. Do not over-tighten the bezel
when reassembling the gauge.
