How do you remove a fuel tank?

To remove the fuel tank, start by relieving the pressure by removing the fuel tank filler cap and relieving the fuel system pressure. Then, disconnect the cable from the negative battery terminal and use a siphoning kit to transfer the fuel into an approved gasoline container. Next, raise the vehicle and secure it on jackstands. Remove the frame brace and, if applicable, the shield over the fuel tank. Disconnect the fuel supply and return lines, as well as the evap vapor lines from the vapor canister. Remove the fuel filler hose from the tank and disconnect the electrical connectors from the tank pressure sensor and the evap vent valve. Position a transmission jack under the fuel tank to support it, and remove the brace that passes under the tank. Unscrew the fuel tank strap bolts and remove the straps. Lower the tank slightly and disconnect the electrical connectors from the fuel pump module. Finally, lower the jack and remove the tank from the vehicle. To install the fuel tank, simply reverse the removal process.

What are the precautions to take when cleaning and replacing damaged fuel tanks in Chevrolet Trailblazer?

Fuel tanks in vehicles are not repairable and must be replaced if damaged. Even after cleaning, there is a risk of explosive fumes. When removing the tank, avoid sparks or flames and if the fuel tank is removed from the vehicle, it should not be placed where sparks or open flames could ignite the fumes.
