Leaking gasoline under vehicle.Gas line leaking at connection to gas tank.Replacement gas line is discontinued and replacement can not be found.

I HAVE A FLEET OF 2011-2015 CHEVROLET EXPRESS DIESEL CARGO VANS FOR MY BUSINESS. EACH OF THEM ARE ON THEIR 3RD REPLACEMENT OF THE DEF TANK HEATER KIT GM P/N 84412924. IT SEEMS TO DIE AFTER USE IN THE 80,000 MILE RANGE. SEEMS TO BE A POORLY DESIGNED PART HAVING TO DO THIS.

VEHICLE WILL SHUT OFF WHILE DRIVING. NO WARNING SIGNS. WILL LOSE ALL POWER STEERING AND UNSTABLE CONTROL. WILL NOT START AFTER IT SHUTS DOWN FOR UP TO 24HRS. THIS VEHICLE ALSO HAS A HISTORY OF HARD/TROUBLE STARTING. WHEN IT TURNS OVER IS WILL GO INTO PROTECTION MODE "LOSS OF POWER". THIS PROBLEM STARTED AT 3,178 MILES AND HAS CONTINUED REGULARLY UP TO THE CURRENT 26, 050 MILES. JACK WILSON CHEVROLET OF SAINT AUGUSTINE HAS ATTEMPTED TO REPAIR THIS VEHICLE ELEVEN (11) TIMES SINCE THE 2ND DAY AFTER PURCHASE. AFTER OBTAINING ALL SERVICE RECORDS SINCE THIS VEHICLE WAS NEW THERE HAVE BEEN 24 ATTEMPTS AT REPAIRING THIS VEHICLE WITH NO SUCCESS. HERE IS A LIST OF REPAIRS PULLED FROM GM WORKBENCH SERVICE RECORDS. CONTINUAL CHECK ENGINE LIGHT. DEALER CANNOT FIND THE ISSUE. TO DATE - I SOLD THE VEHICLE BACK TO DEALER, THEY ARE SELLING, SO IT WILL BE BACK ON...
