System Testing

  1. Remove the fuel pump module access cover.
    2. IMPORTANT: If the floating indicator registers any flow after stabilizing, a leak is evident.
  2. Ignition OFF, install the J 41413-200  (J 41413-100) and the GE-41415-50  . Test for a fuel leak while the system is under pressure referring to the J 41413-210 Operation Manual.
  3. Using the J 41413-200  (J 41413-100) and the J 41413-210 Operation Manual, introduce smoke into the evaporative emission (EVAP) system. Inspect for leaks in any of the following locations:
    • The fuel tank, the fill limiter vent valve, the pressure relief valve, and the grade vent valve
    • The fuel pump module housing, the fuel pump module seal, the fuel pipe, and the EVAP pipes
    • The fuel tank pressure (FTP) sensor seal
    • The fuel fill pipe and hose
