Air suspension push in fittings issues

[biohazardbill]

So doing an air test on my truck i set all 4 airbags to max height and let it sit over night.

Rear bags both dropped about 3 lbs, front left dropped 5 lbs and right front dropped 30.

I figured the the that had small drops in pressure was possibly due to temp change during the night.

So I disassembled the pass side and re sealed the fittings, reassembled, retested all was well.

So I had to reroute my lines for other reasons.

Rerouted pass side and drivers side front. Tested. drivers side now drops in pressure over night. Took apart resealed, retested, pass side now dropping over night and I didnt even touch that side since the previous test.

Rear has had no issues however really dont have any weight on it either.

Ideas?

Swap out fittings for compression fittings?
