Fuel manifold under the back seat of the vehicle was cracked due to the wiring harness placement and pressure from occupants in the back seat caused the manifold to crack and spew fuel all over the electrical harness. Poor placement of the electrical harness for the fuel pump or poor engineering caused this manifold to crack. Very dangerous having fuel leaking out at a high volume onto the electrical connection to the fuel pump. Fire and or explosion danger!!!!.
