Does anyone know where I can find a replacement air brake pressure gauge that goes in the dash. I have a 2000 Marathon Coach. I checked with Prevost parts and they stated that the vendor no longer makes that exact gauge. The new gauge is totally different.

If you want an exact match, try a junk yard. Otherwise, settle for a different look. Here's one example.

What happened to it that has u wanting a new.

Interesting photo of the back. It appears that yours have 1/4 plastic air line going in. Ive always seen 1/8in plastic on these buses. Good to see Prevo got rid of that stuff there.

Had the coach in being serviced. Told them the air pressure instrument light was out. They put new bulb in. Only problem was the bulb they installed was a 12V, not a 24V as it should have been. Bulb blew up inside the guage the first time I drove at night.

The gauge should still be good or how did the explosion damage it? If it ruined the socket prevo should have that.

The glass blub exploded into fragments inside the guage, now the needle which shows your pressure does not move.
