How do drain a fuel tank on a 1978 cj7?

To drain the fuel tank on a 1978 CJ7, first ensure the vehicle is turned off and in a well-ventilated area. Disconnect the fuel line from the fuel pump and place it in a suitable container to catch the fuel. You can then either use a siphon pump to extract the remaining fuel or remove the tank entirely for draining. If removing the tank, disconnect any straps and fuel lines, then lower it carefully.
