Fuel lines to injector rails disconnect
I know this may sound stupid to a lot of you, but I am having fits trying to disconnect the fuel rail steel supply lines to remove the fuel rails and injectors to change my intake. I bought the Lisle tools and I can feel the tool go in and hopefully rerlease the clip, but I can't get the line to separate. I first thoughtr the weakness in my 77 year old hands were the problem. I asked my son-in-law to try and he can't get them to sepsarate either. What am I doing wrong or is there a trick I don't know about? I would sure like to know what I am doing or not doing wrong.
Respectfully asking for help,
Oh it might help to know I am working on a 1991 5.0 mustang.
