hey guys.

recently my Air Lift tank was unable to hold a steady pressure and has been leaking air. After 2 days of not driving, it dropped to 0 PSI. the pressures in 4 corners are still perfectly fine and the car is driveable with no problem.

I've been spraying soapy water around the tank's fitting area, connectors trying to find a leak but no success.

I've contacted Fender Defender (great shop in SoCal who installed my system) and they said there are 5 other people have been experiencing the same problem, all with Air Lift system, and they suspected that the Manifold is the culprit of the problem.

I will try to spray more soapy water on the manifold tonight and report back my finding.

 

Sorry I can't help but I would be interested in if you have heard anything since or solved the issue, I was actually looking to get the Airlift 3H management kit in the near future and never heard anything bad about them

 

I found the problem!

The leak was from my SMC check valve. See the video below.


You can hear the air leak when I move the leader hose back and forth. The SMC valve was dirty when I removed it. The dirt block it from closing all the way, causing the leak. I cleaned it and put in a new valve and save that one for back up.

All are good now!
