You guys are crazy............Push IN on the clip and the hose releases instantly, it's a quick release fitting. No need even to take it apart. When on assembly line the assembly tech simply pushes hose in and it locks. There are small teeth inside that grab hose, pushing ring in releases them.
You can find same type fitting at Home Depot in plumping department but Ford in its' infinite wisdom has made sure to use bastard one off size so not easily replaceable.
