CAUTION: Use the EVAP Pressure/Purge Diagnostic Station (J-41413) in order to provide a clean, dry, low pressure gas source. Do not substitute any other pressurized gas source. Damage may result to the EVAP system. Proceed with the following procedure only if referenced by an EVAP diagnostic or repair procedure.
