Circuit/System Testing

IMPORTANT:
  • Larger volume fuel tanks and/or those with lower fuel levels may require several minutes for the floating indicator to stabilize.
  • Refer to J 41413-200  (J 41413-100) operation manual for detailed instructions.
  1. Using the GE-41415-50  , connect the J 41413-200  (J 41413-100) to the vehicle filler neck.
  2. Seal the system and use the flow meter on the J 41413-200  (J 41413-100) calibrated to 0.51 mm (0.020 in) to determine that there is no leak in the EVAP system.
    • If a leak is detected, use the J 41413-200  (J 41413-100) to apply smoke to the EVAP system at the service port or the filler neck until the leak is located. For vehicles without a service port, disconnect the purge tube at the quick connector on the EVAP canister side of the purge solenoid valve and install the CH-48096  . See Special Tools .
