How do you replace the fuel pump in the port injected turbocharged on Buick Regal?

The 1986-87 port injected turbocharged V6 engines incorporate an electric fuel pump mounted internally within the fuel tank, requiring tank removal to get at the pump. Before removal of fuel lines it is necessary to release pressure in fuel system to avoid such a dangerous phenomenon as high-pressure fuel spray; and all sources of fire, spark or naked flame must be omitted from work area. First remove the power supply to fuel pump and crank the engine until the engine dies and turn on the starter to release the pressure from fuel pump. Remove the negative battery terminal and then to proceed to empty the fuel tank if possible, using either a pump or a siphon prominently. Lift up the vehicle high enough as recommended for tank removal and then stabilize the tank and the supporting strapping bolts and spacers. Slowly pull the tank down in order to remove the terminal of the fuel gauge sending unit then set the tank aside. Leverage and pull the cam locking ring and then remove the fuel gauge sending unit/pump assembly then remove the pump assembly attached to the sending unit check for damages at the attaching hose and the rubber sound insulator. Replace the new pump assembly with the new O-ring and put back the tank in reverse as mentioned above. For fuel system pressure testing, connect the harness and bring the ignition ON;To check the pump, ensure it runs and confirming fuel pressure values. If pressure is out of that range, electric FOR, look for leakage, ensure pressure control regulator and fuel filter from contaminants. Should further tests be required, one needs to pinch the fuel return line and check the pressure in order to diagnose fuelling related problems with the fuelling system's components. Before doing any work on all of the fuel system elements, there must be a discharge of the fuel system pressure.
