And I believe it is the reason my FRONT AIR light is on... what is it? I received this PDF from Prevost... and the guy is nice and all but knows about as much as I do and without the first person view of the gizmo... anyone able to tell me what it is and what the part off the attached sheet is? Is this something I can buy from a local NAPA/AdvanceAuto place or do I have to get this from Prevost?


I’m looking to get this thingy right away so I can drive my coach.....

Did he say it was part 80 or 81? Do you have a low pressure light on? Any warning lights? If no, disconnect the 2 wires and short them together and see what warning light you have. If its 80/81, you can pick one up at any truck parts place. The activation pressure is likely 60-70 psi.
