first you would open the gas cap to relieve pressure from tank. then under the hood you need to fine the pressure value for the fuel line and release that pressure as well once the pressure is out you will have to remove the two bolt screws ateach end of the filter. have extra rags and something to catch the excess fuel. the fuel line on the engine side of the filter is held in place in a plastic snap fitting. unsnap it and the line can be moved out of the way to remove the filter. then replace and go in reverse to install new one. about 30 minutes to change. dont change filter often you could damage the pump or O2 sensors.
