Hi guys is there any diesel maniacs out there. The fuel injectors went out on my truck and I'm trying to replace them myself. I've got the Ford books which I'm finding out is not much help. I've got the valve covers off of it and now trying to get the steel flex line off of the injector fuel rail with no success. I bought the special tool that Ford said I had to have but it has been of little help and the book tells me nothing about how to use it. Spent about three hours on the internet and no instructions or pictures I'm assuming that is a quick disconnect coupling but have no idea how it comes apart. Here is a picture of what I am trying to take apart. Any help will be appreciated. Thanks Mitch
