Begin by removing the cable from the negative battery terminal, ensuring to disable the anti-theft feature on models with a Delco LoeII audio system. Next, take off the filler cap from the fuel tank and drain all fuel into a clean container, using a siphon through the filler neck or draining via the fuel line to the carburetor or fuel injection unit, as there are no drain plugs. Raise the vehicle and support it securely on jackstands, then disconnect the exhaust pipe from the rear of the catalytic converter and allow the exhaust system to hang over the rear axle assembly after disconnecting the rear exhaust pipe hanger. Remove the exhaust pipe and muffler heat shields, followed by the fuel filler neck shield. Proceed to remove the rear suspension track bar and its brace, then disconnect the fuel gauge wiring harness connector. Detach the tank ventilator hose, fuel vapor hose, and fuel feed and return hoses from the sender assembly by loosening the hose clamps and pulling the hoses off the fittings. Remove the fuel line retaining bracket on the left side and the brake line clip from the bracket. Position a floor jack under the rear axle assembly and raise it just enough to relieve the weight off the axle, then disconnect the lower ends of the rear shock absorbers. If applicable, remove the rear stabilizer bar from the frame, then lower the jack enough to allow for the removal of the rear coil springs. Remove the fuel tank supporting strap bolts and take out the fuel tank by rotating the front down and sliding it to the right, ensuring that the brake lines and cables are not stretched or damaged. The installation process is the reverse of removal, and once completed, check all lines, hoses, and fittings for leaks.

If the fuel tank is removed from the vehicle, it must not be placed in an area where sparks or open flames could ignite the fumes.
