1999 GMC Suburban

The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. The tank was installed in September 2021. The tank began leaking in February 2022. A repair shop discovered that the tank was defective and had failed. The Tank was discarded and replaced with a new unit. As no OEM parts are available the replacement was also and aftermarket part. That tank also was defective and began leaking within 90 days. A third aftermarket tank was installed and it also began leaking recently. When these leaks occur the tank fails in such a way that a large volume of fuel is spilled collects under the vehicle. As there seems to be only one company manufacturing these parts there seems be be a large potential that the issue will affect many vehicles.

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.
