- Install New Intake Manifold Gaskets: Place new intake manifold gaskets onto the cylinder heads, ensuring they are properly aligned with the ports.
- Install the FiTech Intake Manifold: Carefully position the FiTech 37855-2C manifold onto the cylinder heads, aligning it with the gaskets and bolt holes.
- Install Mounting Bolts: Install the intake manifold mounting bolts and torque them to the manufacturer’s specifications in the correct sequence.
- Install Aftermarket Fuel Rails: Mount the aftermarket fuel rails onto the FiTech intake manifold.
- Install Fuel Injectors: Install the chosen fuel injectors into the fuel rails.
- Connect Fuel Lines: Connect the fuel supply and return lines to the fuel rails. Ensure all connections are secure and leak-free.
- Install Throttle Body: Mount the throttle body to the intake manifold.
- Reconnect Vacuum Lines and Sensors: Reconnect all vacuum lines, sensors (like TPS and IAC), and wiring harnesses that were disconnected during the removal process.
- Install Throttle and Transmission Cables (if applicable): Reconnect the throttle cable and transmission kickdown cable, adjusting them as necessary.
- Check for Leaks: Before starting the engine, double-check all fuel and vacuum line connections for leaks.
- Reconnect Battery and Test: Reconnect the negative battery terminal and start the engine. Monitor for any leaks or issues.
