Westport Fuel Systems vent hole associated with the pump pressure relief valve may have been covered by a welding process, during the manufacture of the pump.
The short version
WESTPORT FUEL SYSTEMS INC reported a problem with the delivery fuel pump. Here is what owners need to know.
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.
THIS COULD RESULT IN A SUDDEN LEAK OF HIGH PRESSURE GAS WITHIN THE TANK SHROUD AND A SLOWER LEAK OF TANK PRESSURE, WHICH COULD RESULT IN PERSONAL INJURY AND/OR VEHICLE OR PROPERTY DAMAGE.
WESTPORT WILL INSPECT AND CORRECT THE PROBLEM BY UPGRADING TO AN AUTOMATIC SHUT-OFF VALVE THAT DOES NOT USE THE VENT HOLE, free of charge.
