As all Chevrolet car: dismantle the fuel tank completely. Place your above to get free accees below taking into account the space necessary to down the fuel tank.Drain the fuel tank , then disconnect battery BOTH + and -. Have a fire extinguisher nearby. Dismantle the rubber pipes connected on the tank. Unscrew the 4 bolts that sustain the tank braces. You need to be 2 person to bring down the tank. Disconnect the electrical connector. Unscrew the 6 bolts of the pipes and cable penetration above the tank. Pull out carefully the fuel pump assembly. To reinstall, first clear dry the tank, change rubber gasket and at least electrical harness and the pump and its strainer. This pump is a design weakness of these models of chevrolet. Each time to down the tank (roman work!!) better to change the pump and strainer anyway. Courage

The fuel pump is mounted in fuel tank. To get it out, you have to take off complete fuel tank and drag it out with fuel pipes. Its a night mare, I did it.
