Fuel Rail & Injectors (SFI): Installation
- Install fuel pressure regulator to fuel rail and tighten bolts to specification. See TORQUE SPECIFICATIONS . Install NEW "O" ring and grommet to each injector. Lubricate new injector "O" rings with clean gasoline. Install injectors to fuel rail so that injector connectors will point upward. Install 4 NEW insulators and 2 spacers on intake manifold.

If injectors are tight and will not rotate smoothly, reinstall with NEW "O" rings. Tighten fuel rail-to-intake manifold bolts. Install fuel intake hose to fuel rail and tighten bolt to specification. See TORQUE SPECIFICATIONS . To complete installation, reverse removal procedure. Refill engine cooling system.
