Fuel Tank Removal

If yours is like my son's '74 Dart Sport, the filler neck pokes through the quarter panel and is held in place with three screws hidden under the gas cap. The filler neck then slides through a rubber boot attached to the trunk floor. Finally, the neck goes through a gas tank rubber grommet. If the boot and grommet are both original, or at least several years old, they are probably stiff and stuck to the filler neck. Friction is your only hurdle to overcome, nothing else (except the three screws I mentioned) hold the neck in place.

As stated above, use a screwdriver or utility knife and separate it from the boot and grommet. You can try to work the neck up out of the quarter panel by twisting, pulling, and prying. But it might be easier to drop the tank, so its weight is working in your favor. Just make sure to use a floor jack so you can ease it down under control. I would certainly siphon out the bulk of the gas before starting this chore. The sloshing gas makes the tank unsteady.
