Fuel Rail & Injectors: Installation
- Lightly coat new injector "O" rings (fuel rail side) with fuel. Install new insulator in intake manifold. Rotate injector while pushing into fuel rail. If injector does not turn smoothly, remove injector and check "O" ring for binding.
- Lightly coat new injector "O" rings with fuel (intake manifold side). Position fuel rail assembly over insulators. Install injectors in intake manifold. Ensure injectors rotate smoothly. If not, check "O" ring for binding.
- Bolt fuel rail assembly to intake manifold. Connect high pressure fuel hose to fuel rail. With ignition on and engine off, check for fuel leaks before starting engine. To complete installation, reverse removal procedure. See TORQUE SPECIFICATIONS table at end of article.
