If your doing the feed line the front section goes in with zero issues. The rear section I also lifted the body up a few inches . If your rear fillers are still good I suggest removing your rear bumper. If your car is rusty enough to have rotted lines then there is a good chance that some of the body mounts are gonna be rotted or broken bolts, or the frame may be rotted around where the mounts go. I suggest if you have a problem with fuel feed front just replace that one and not deal with the other for now. If the back is bad replace them both and be ready for headaches
