The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. This tank included a new fuel pump lock ring, which was used to secure a new fuel pump in the tank prior to installation in the vehicle. The lock rung failed approximately one week after installation allowing the fuel pump to raise up out of the tank. At the next fuel up a large volume of gasoline escaped form the fuel pump opening and spilled. The defective lock ring was replaced with a OEM part and was subsequently discarded.

MY 1999 C1500 SUBURBAN CAUGHT FIRE WHILE PARKED AND COMPLETELY OFF. IT HAD BEEN PARKED FRO 9 HOURS WHEN WE WERE AWAKENED AT 2AM BY NEIGHBORS AND POLICE TRYING TO EVACUATE OUR HOME. THE CAR BURNED TO THE GROUND AND WAS THE MOST FRIGHTENING EXPERIENCE. I HAVE A 9 AND 6 YEAR OLD THAT ARE TRAUMATIZED BY THE INCIDENT. I REPORTED THE MATTER TO THE GMC CUSTOMER CARE AND THEY REPLIED SAYING THAT THEY WOULD CONTACT ME IN 2 DAYS. THIS IS UNFORGIVEABLE.
