When a hose is reinstalled or replaced, the following points are essential:
  • Route hoses in the same position they were in before removal.
  • Route hoses smoothly; avoid sharp bends and kinking
  • After hoses are installed, check for leaks while the system is being bled.
  • Tighten the hose connections to 28 Nm (20 ft. lbs.)

do i need to remove the pump to attach the high pressure line? What is the easiest way to bleed the system
Expert:  Dave Nova replied 5 years ago.
The pump does not need to be removed to replace the high pressure line. sometimes it is easier to break the fitting loose by working from underneath with a wrench.

Open diagram below for bleeding procedure.
