Fuel Rails & Injectors (LS400 & SC400): Installation

  1. Install new "O" rings and grommets on injectors. Using a twisting motion, push injectors onto fuel rail. See Figure. Install insulators into injector holes in intake manifold. Install injectors together with fuel rail, and lightly tighten nuts. Ensure injectors rotate smoothly left and right. If injectors do not rotate smoothly, recheck "O" ring installation.
  2. To complete installation, reverse removal procedure. See TORQUE SPECIFICATIONS  table. Fill cooling system with proper mix of water and coolant. Ensure cooling system is properly bled. Start engine, and inspect it carefully to ensure no fuel or coolant leaks exist.
