Fuel Rail Cleaning

After all components have been removed, flush the fuel rails with a solvent. Use compressed air to remove any remaining solvent.
IMPORTANT: If a mechanical failure has occurred with the air compressor or direct injector assemblies, the fuel rail must be
disassembled and flushed with a solvent to remove debris.

Fuel Injector Installation

1. Inspect the fuel injector plastic body for heat damage. Replace as needed.
2. Inspect the fuel injector nozzle for debris. Replace as needed.
3. Install new O‑rings onto the fuel injector.
4. Lubricate the fuel injector O‑rings with 2‑4‑C with Teflon.
5. Install the fuel injector into the fuel rail. Turn the injector back and forth slightly to seat the fuel injector O‑rings into the fuel
rail.
6. Lubricate the fuel injector retainer screw threads with 2‑4‑C with Teflon. Secure the fuel injector to the fuel rail with the retainer
and two screws. Tighten the screws to the specified torque.
