- Install NEW grommet on each fuel injector. Coat NEW "O" ring with gasoline and install "O" ring on each fuel injector. Use twisting motion when installing fuel injector on fuel rail. Position electrical connectors on fuel injectors toward outside of fuel rail. Ensure spacers and NEW insulators are installed on intake manifold.
- When installing fuel rails, install fuel rails with fuel injectors on intake manifold. Loosely install fuel rail-to-intake manifold nuts. Using NEW gaskets, install front fuel pipe and front fuel pipe-to-fuel rail union bolts on front of both fuel rails. Install front fuel pipe clamp bolt in clamp at center of front fuel pipe. Tighten front fuel pipe-to-fuel rail union bolts and front fuel pipe clamp bolt to specification. See TORQUE SPECIFICATIONS .
- Install clamp and fuel return pipe-to-fuel rail clamp bolt on rear of driver's side fuel rail. Tighten fuel return pipe-to-fuel rail clamp bolt to specification. See TORQUE SPECIFICATIONS .
- Ensure fuel injectors rotate smoothly. If fuel injectors fail to rotate smoothly, check for improper "O" ring installation. Ensure electrical connector on each fuel injector is facing toward outside of fuel rail.
- Tighten fuel rail-to-intake manifold nuts to specification. See TORQUE SPECIFICATIONS . To install remaining components, reverse removal procedure. Use NEW gaskets when installing fuel pulsation damper.
- Using a torque wrench and Steering Rack Wrench (09617-24011), tighten pulsation damper to specification. See TORQUE SPECIFICATIONS . Install negative battery cable. Operate fuel pump and check for fuel leaks.
