Locate the fuel lines. They are located under the truck, near the gas tank.
Use a wrench to loosen the nuts that hold the fuel lines in place. Be careful not to drop the nuts into the gas tank.
Once the nuts are loosened, you can remove the fuel lines from the gas tank.
Be sure to cap off the fuel lines to prevent fuel from leaking out.
You may also need to remove the fuel filter before you can remove the fuel lines.
Once you have removed the fuel lines, you can remove the gas tank.
