Air leak on M925A2 , Air dryer line?

[wheelspinner]

That should be in-line with the CTIS module, on the yellow line.

There is one in and one out its the air feed and fill air out from the ctis valve body. The little filter thing is on the fill line. They both connect to copper line on the way thru the firewall. If you look by the governor on the engine side of the firewall the copper ctis feed line usually has a loop before it goes in.

Yes sirs I see it. Any ideas on where to get a replacement? Im not sure why mine leaks air from the bottom port unless its just old.


Also does the CTIS valve body make a sort of buzzing sound or should it be quiet ? I have one that makes noise and one that makes a very quiet sound.

The valve body makes noise but not continuous. See if a standard schrader valve from a tire stem will screw into the bottom of the little filter where the air is leaking. There is also an oring where you screw the basin piece on.

The insides of mine have a tiny bit of rust and the parts look pretty old. If you guys know where I can buy a new one it would help a lot.

You can just clean it out good I used a toothbrush and some soap on mine and put it back together it's been fine for some time now.
