I am attempting to change the fuel filter, noting works to disconnect the lines. on 1997 Ford F-150

the lines going into and out of the filter are braided high pressure held into place with a quick connect of some I have not encountered...strange looking clamp that hooks down into the fitting after it is locked onto the filter nipple...all of my quick disconnect tools will not work to release this line...any ideas?
