Engine
If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.
The engine may stall and fuel may leak due to overheating of the electrical terminals in the fuel pump module, resulting in the melting of the flange material. Dealers will replace the fuel module and fuel tank jumper wiring harness free of charge to resolve the concern.
