One of the 4 fittings that connect to the FEL is leaking all at once. It was tighter than normal when disconnecting. It is a steady fast drip.
What might it be?
Is it leaking after you disconnected it? Probably a bad o-ring inside and the connector needs to be replaced.
The previous owner of my TC29D replaced all the quick connects with these flat style which are much easier to clean before I reconnect them. I give them a quick shot of brake cleaning spray to get all the dirt off.
