Which part brust? I beleive there is two lines between the junction block at the front and the flex hose at the rear (unless mine just wasn't factory).
Also, it will be easier to get the fittings out without stripping them and swearing if you cut the line right before the fitting (obviously the line you are replacing) and putting a socket on the fitting.
You should be able to install pre-bent lines without any tools other than a couple wrenches (as long as the fittings come out easy)
