Fuel filter removal

I attached the process but I imagine the issue you are having is how to actually unhook the connections. If so, you need to use the tool pictured with the proper size. You just slide that over the line and push it into it to release the spring inside the line then pull the actual fuel line away from the filter to remove it. Then to reinstall on the new filter just push it on until you hear is click.

Let me know if you have questions. Thanks
