  WESTPORT IS RECALLING CERTAIN ISX G CLASS 8 VEHICLES EQUIPPED WITH LIQUEFIED NATURAL GAS PUMPS. THE VENT HOLE ASSOCIATED WITH THE PUMP PRESSURE RELIEF VALVE MAY HAVE BEEN COVERED BY A WELDING PROCESS, DURING THE MANUFACTURE OF THE PUMP. THIS CAN RENDER THE PRESSURE RELIEF VALVE INEFFECTIVE, RESULTING IN THE POSSIBLE BUILD UP OF GAS IN THE PUMP IF THE MANUAL SHUT-OFF VALVE IS CLOSED.
