You can fix it easy. Dunno about freightliner Volvo dealer does have o-rings and collars for quick connect. really cheap.
Disconnect the hose, pull collar out with long nose pliers. Use tools from paper clip to pull out o-ring. slide in new o-ring, new collar and connect the hose. Check for leaks.

honestly, ive fixed so many of those leaks from those big push fittings its just not worth it. Grab a real 90 degree compression fitting and remove that POS and put a proper fitting in there. quick connects suck and leak with cold, vibration, or just cause they want to. Compression fittings when installed properly very very rarely leak.

i see this so many times on blown apart fanhubs, a push fitting on the air into it and its leaking but you cant hear it. it causes the hub to never fully disengage and burns the hub out in short order. never ever ever use a shitty push fitting on a fanhub.

if i owned the truck it would not have a single push air fitting on it, i would install proper fittings in every spot possible.
