[AT] Chevroplet 8500 Air brake issue

[Dennis Johnson]

Cecil,

I used to use these on oil field control consoles. Most of the ones I have seen have sleeve around the tubing that needs to be pushed in to release the tubing. I have seen some tools that look like a half section of a piece of tubing.

Thanks
Dennis

Cecil,

Seems to me that there is a tool for easily disconnecting them, remember seeing them somewhere. Maybe it was at Harbor Freight or maybe Autozone. For the ones that I use on our reverse osmosis system, I’ve learned to use a small screwdriver to make the disconnection, but them I have plenty of room to do so.

I have an air leak under the dash in my C8500 1998 Chevrolet tractor mover.  I have the instrument cluster out and can barely reach to the fittings in the firewall.  Ther eis one line that goes from the parking valve to over the top of the steering column to who knows where.  My leak is somewhere beyond the air valve.  It really hisses.  I have replaced nearly all the fittings last spring on this thing.  I have an alcohol tank ordered.  Those quick connect fittings are a pain in the butt...  Does anyone have any experience with these..  Maybe Steve W..???  The factory service manual is $300+, and I have tried to download 2 times today and it failed.  I will wait until tonight after midnight to download...
