It connects to the main line with a short length of rubber fuel line, and has a threaded connection to the fuel pump. It clips to the subframe using spring steel line clips available from Inline Tube and probably the other vendors as well.

These lines ARE available separately through those vendors I listed earlier by inquiry. They manufacture them in sets but if they have a run going can easily add one to the run, or may have a spare if the other part was damaged in shipping and returned.
