Default Air Suspension help/favor!

Evening, My 2012 overland has decided to turn into a hot wheels. After a few hours the front is sitting so low the tires are above the guards. On start up it comes good but leaks out when parked. I could hear the left one leaking so wiggled the connector at the end of the air hose and as I twist it left or right air pours out. I was going to order new L connections but was hoping someone could check if theirs (that isnt a hot wheels) does the same or not. I just swiveled it less than 60' and it leaks. Both sides do this. Attached a pic to show what I mean.
Also could someone take a quick pic of the Right front side in the general area of the strut tower. My air hose is routed over the fuse box which I know isnt right. If i try move it it leaks, Guessing something as been done in the past. Cheers.

The connections shouldn't leak. Mine don't.
The Quadralift is a closed system - means it has stored nitrogen in a tank behind the rear seats that the compressor uses to pump up the bags - when the system is lowered the nitrogen returns to the tank. It doesn't get fresh air from anywhere. I guess there's no reason why it wouldn't work on air - but moisture inside the system is likely the enemy.
Ive not heard of anyone sourcing components anywhere but from Jeep - here or from the US forums.
It MAY be that the fittings are the same as Mercedes systems due to the heritage of this model.
Once you have the fittings you will need to have the system refilled and pressurised and once again I've never heard of any alternative to Jeep.
No better news from me unfortunately - but you could look up your closest Jeep specialist mechanic and ask…..
John

Thank you so much for the details and the response. I hadn't thought about it being a closed system, and was just using the concept of and air compressor type function. The jeep is booked into Jeep but due to the amount of airbag recalls they are doing cant get in until the 16th of next month, don't really want to drive the hot wheels too far! I was thinking of replacing the L connectors myself. Pulled one off last night. Only a little air (nitrogen) escaped. Out of curiosity does the rear work on a different tank?

This is the part.

Just so you know nitrogen is used because it is an inert gas. It won't expand or contract with changes in temperature or pressure. If air is used, the pressure varies due to heat while driving so adjustments need to be made constantly and could be a pain offroad in corrugations.

This is the same reason nitrogen is used for pressure testing air conditioning systems.

Your passenger side run looks OK.
Your drivers door line runs over the fuse box as you mention - and that route takes a significant shortcut.
On mine the line on that side runs up from down near the compressor, parallel with and alongside the top of the guard and pretty much turns 90deg out to the top of the strut. Out of the way of everything.
Just an opinion but your line looks like it may have been shortened - or the slack is somewhere else in the run.

Great news. Had the air hose connections shipped from the US. 150, half of that was shipping. Jeep wanted 280, comes with entire lines. Fitted and leaks stopped. Car holds height now! Still need a refill as lost so air and won't go to max height but very happy with the fix. Cheers all
