One problem related to tank assembly has been reported for the 1996 GMC Suburban. The most recently reported issues are listed below.
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.
