How do you disable the fuel system when changing the fuel filter? When I changed it the last time fuel continued to come out the fuel line. Most cars that I have changed fuel filters on the gas eventually stops.

You have to discharge the pressure in the system. On most you remove the fuel pump relay or fuse. Start the engine and let it run until it shuts down. Then change the filter. You will still get leakage but it should not be as bad.
