What owners say
Fuel leak due to fuel pump wiring and connector. Lost 3/4 tank of gas.
Fuel leaked from the tank after the consumer put gas into the vehicle. The differential broke which caused a grinding noise. *nm the vehicle was taken in for service and found that the elevtrical wires around the neck of the tank were melted and the tank had to be replaced. Consumer stated that the short in the electrical lines could have cause a fire. On a road trip the vehicles right rear break started grinding into the pads.
Wiring to fuel pump inside of gas tank getting hot enough to melt wire insulation and plastic connector resulting in gas leak at fuel pump module. Had replace fuel pump module, but its my concern that a fire could be caused by overheated wires inside of fuel tank.
After filling up with gas at sam's, I drove down to the sams store to make purchases. When I returned to my vehicle, a pool of gas was underneath and beside my suburban causing a huge fire hazard. The fire dept. Was called to the scene and offered to escort us to our choice of repair location. The local chevrolet dealership replaced the fuel module which they said had "gone bad" and caused fuel to be pumped out of the tank. The possible hazards to me and my family associated with this fuel leakage terrify me.
Consumer states the fuel pump module (connector) was leaking fuel due to a fuel pump wire that had melted inside the fuel tank. *ak gm replaced the 10-amp fuse with a 20-amp fuse. This caused a fuel leak. Consumer wondered why the fuse didn't blow to prevent leakage. Gm did offer a 45/55 split but the consumer wouldn't be informed of the findings after an investigation was completed. *ph
The consumer discovered gas leaking from under the vehicle. The dealer stated the electrical over heating of the fuel pump module caused the leak. The wires entered the fuel tank charged and caused the cap to melt/deform which resulted in the leakage.
While driving noticed a fuel leak.

- What is wrong
- Certain trucks and sport utility vehicles were built with fuel module reservoir assemblies that contain fuel pump wires connectors may overheat under certain operating conditions.
- Risk
- If the ignition circuit wire is exposed, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. If sufficient heat is conducted to the pass-through connector, a hole in the connector may result, which may cause a 'service engine soon' light to be illuminated during the emission system diagnostic routine. Fuel vapor and in some cases liquid fuel may leak out of the fuel tank through the hole in the connector body. Fuel leakage, in the presence of an ignition source, could result in a fire. Also if the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result.
- Remedy
- Dealers will remove the fuel tank, and remove the module reservoir assemblies from the tank, and install a new service kit free of charge. An interim letter to owners was mailed on may 25, 2005. The owners were re-notified on october 19, 2005, since parts are now availabe. Owners may contact chevrolet at 1‑800‑630‑2438 and gmc at 1‑866‑996‑9463.
