disconnecting air lines?

[tikitiki65]

I've got the Air Leveling in my 88 CS. How do you disconnect the line? The manual says to push the retainer in and pull the line out. I've tried that and have been pulling pretty hard on the line and it hasn't budged. Any suggestions? Thanks and happy T-day to everyone.

Try a little penetrating oil and compressed air if you have it to loosen any trapped dirt behind the retainer even brush it clean with a tooth brush.

Then try to push the line in slightly and twist it a little then pull it out while pushing on the orange retainer. They can be stubborn
a small open ended wrench may help you push harder on the retainer.
