I have a strong belief the new clutch master cylinder I installed on this Ranger is bad. Pulling it and swapping it for a new one would not be an issue if I could just pull this one. The problem I am having is the little plastic ring that is used to disconnect the high pressure line is trashed. None of my disconnect tools will fit because there is a lip on the fitting. I have tried other rings with no luck and I have found none in the salvage yards. This truck is deadlined until I get this disconnected. Do any of you have any ideas on how I can do that?
