I detect leak due to each morning the rear end seems to be low. When I open the door, I hear hissing sound seem to me that the compressor is trying to jack up the air spring.
Now I am at the point to disconnect the BIG BLACK PIPE from Air Bag. I try to follow instruction of

I just could not release it. Any suggestion? (I already release the air from the air bag since I can squeeze the air back through compressor and air escaped from compressor release valve.)
I answer my own question:
Just squeeze the clip and pull. there is no downward movement. No force really needed here.
As you can see in the 2nd picture bellow, when squeezed, black clip lip inside the tube disappeared. 3rd picture shows clips related to this job.
