Tank Assembly Problems of GMC Suburban

Arcing connector inside fuel tank causes fuel pump to fail and loss of engine power. Gm technican reported that he performs at least 2 replacement senders + fuel pumps/week- indicating that " the sender/fuel pump connector is always fried when the pump goes". As an engineer, I believe there is an eminent danger of a fuel tank explosion provided proper air/fuel ratio is achevied. Vehicle has 42 gallon tank. Model years 1999 onward have this assembly encased in fiberglass cylinder which would prevent fire/explosion.

While driving daughter to school, pulled into the parking lot and vehicle stalled, and would not start again. Had vehicle towed to the dealer, and they broke the fuel sending unit. Which they replaced. But, still having problem with vehicle stalling. Engine check light came on and stayed on. They pressurized the tank. Now the gas gauge does read properly.
