Aura leak on dark orange air supply hose.

The hose might be chafed from them being bunched together. The hose cam be replaced easily if it comes off the firewall. Should be a push fitting so you can pull the line off and patch it. It'll say the size of the air line, so your call on doing it yourself or a shop. You can do that in a parking lot if you had to.

 

Total cost if you did it yourself would be a few dollars. Just a matter of finding the leak and then getting a patch kit. Or replace the entire hose. Home depot has union fittings and such, I carry a few of every size for emergencies.

 

Selam Ercan, if there is a brass ring where the orange hose enters the fitting,take a small screw driver and use it to push in on brass ring,as you push pull the hose out (you may wiggle it bit) cut the hose about 3/4 inch and push the hose back in to fitting ,you are done.
