Reverse removal procedure for installation noting the following.

• Replace injector O-ring (1) and insulator (7) with new one using care not to damage it.
• Check if cushion (2) is scored or damaged. If it is, replace with new one.
• Apply O-ring oil to O-rings (1), and then install injectors (3) into delivery pipes (4) and intake manifold.

  Make sure that injectors rotate smoothly (6). If not, probable cause is incorrect installation of O-ring. Replace O-ring with new one.
