It looks to me as if the rubber hose in the first picture is not fully pushed down. Using a pair of pliers, close down on the two tabs on the clamp. It will open it up. Slide it up out of the way. Try pushing the rubber tube down until it reaches the flare on the metal tube. It looks to be about 1/4 inch on the picture. Replace the clamp. Try to clean up any fluid and hope that fixes the problem.
