The same plastic clip as found on an EFI fuel filter holds the pressure line to the pump. The clip will usually be white. Ours is black since our original pump was replaced awhile back with a Ford Racing Performance Parts 190-lph kit. It uses a larger feed line, hence the black clip shown here. Simply pry the old clip out of the line and remove the fuel line, being aware there is still a small amount of fuel in the line under pressure.
