Removing and replacing the fuel door of a Pontiac G6 requires a series of steps. These include relieving the fuel system pressure, disconnecting the negative battery terminal, raising the vehicle and placing it on jackstands, and removing the exhaust system under the fuel tank. It is also necessary to disconnect the fuel filler neck hose, siphon gas, and disconnect the EVAP recirculation hose and canister. Acquiring a serpentine belt removal tool can make the process easier, although it is not required.

What You'll Learn
Relieve the fuel system pressure
To relieve the fuel system pressure, you will need to disconnect the cable from the negative battery terminal. This will ensure that the fuel system is no longer under pressure and will make it safe to work on.
Next, raise the vehicle and place it securely on jackstands. This will give you access to the underside of the vehicle, including the fuel tank and related components.
Now, you will need to remove the part of the exhaust system that is located under the fuel tank. This may involve loosening and removing some bolts or clamps that secure the exhaust system in place. Be sure to support the exhaust system with a suitable jack or stand to prevent damage.
Once the exhaust system is out of the way, you can access the fuel filler neck hose. Loosen the hose clamp that secures the hose to the fuel tank and then disconnect the hose. You may need to use a hose removal tool or a similar device to safely remove the hose without damaging it.
At this point, it is important to siphon as much gas out of the fuel tank as possible. Alternatively, you can drive the car until the fuel tank is almost empty. This step is crucial for safety, as it reduces the risk of fire or explosion when working on the fuel system.
Finally, loosen the hose clamp screw and disconnect the EVAP recirculation hose from the fuel tank. You may also need to disconnect the quick-connect fittings for the fuel and EVAP lines. This will completely relieve the fuel system pressure and allow you to proceed with the fuel door replacement or other necessary repairs.

Disconnect the negative battery terminal
Disconnecting the negative battery terminal is an important step when removing the fuel tank in a Pontiac G6. This is because it relieves the fuel system pressure. To do this, you must first relieve the fuel system pressure, then disconnect the cable from the negative battery terminal.
You should then raise the vehicle and place it securely on jackstands. Next, remove the part of the exhaust system underneath the fuel tank. Loosen the hose clamp that secures the fuel filler neck hose to the fuel tank and disconnect the hose from the tank. Siphon as much gas out as possible, or drive the vehicle until the tank is almost empty.
You can then loosen the hose clamp screw and disconnect the EVAP recirculation hose from the fuel tank. Disconnect the electrical connector from the side of the EVAP canister and disconnect the quick-connect fittings for the fuel and EVAP lines.
Finally, ensure all wires and lines are disconnected, and support the fuel tank with a floor jack and a block of wood.
