Air line behind speedo blew off!
I was pulling into a park in Tx today when there was a loud explosive bang from behind the dash in my 06 Monaco Dynsty. I ground to a halt at the entrance to the rv park as I lost all my air and the brakes set up. I went through the removable dash access panel in the top of the dash. There is a air line that goes to the electronics and converts the pressure, to a signal for the front air tank gauge.
What I need help with is how does this attach to the gauge back. It looks like some kind of pressed in fitting. HELP!

Good explanation of how to do ptc fittings. A flush, smooth, straight cut is important.
Pretty easy really...after the excitement subsides.

To get moving just cap the line or kink it to stop the leak.
Another poster found the fitting for his at motion industries

If it's the fitting, you need a 1168X4A. I went through the same thing in Alaska a few years back.

100% correct on kinking the end of the air line to keep your air. You can get the fitting, most likely, at any pneumatics parts house. I've not checked NAPA to see if they would have them, but I'm thinking not. On our '06 Dynasty, Dixon #31095620 was what I purchased at A1 Coupling and Hose, in Albany, OR. Two of them cost me $11.81. I bought a spare, while I was at it. The one I bought has a 90 degree bend, and it made it a little easier to avoid side forces on the hose once it was inserted. They have straight ones, too.

Would have been kind of scary if this had happened while driving on the highway.

The noise may have been interesting but the air pump has way more volume capacity than a 1/4" air line that is leaking. At highway RPM it wouldn't have been an issue otherwise.

X2...I do not worry about the 3/16 airline to my homemade toad air brake system breaking as other than the pressure dropping and building up more often it's not going to get down to 60 psi and set the spring brakes.

My module just broke where the air fitting goes in, so I need a new module. Anyone have any ideas?

Bill767,
Does your module look like the one in post #4 above?

It is similar, but larger. It contains not only the air line connections, but also all the alert and message info, such as, stop engine, check engine, parking brake, etc.
