3d, you only need 1 tapped bolt and 2 washers for FP connection. If you remote-mount your sender as everyone advises and I did, you'll need a hose barb fitting to thread into bolt, the correct length fuel line[2 feet is plenty] and some hose clamps. When you have the parts in front of you it makes more sense, your local NAPA etc. will have accessories and help. Consider going post filter to "see" what your injection pump is "seeing" . I just did this install so if I can help PM me. Have Fun, Jim G.
