Fuel line fittings
Ford produced three styles of push to connect fuel line fittings so we need to identify which one you have. Most early models used the hairpin and duckbill clip style and are fairly easy to remove. Lines sizes 3/8 and 5/16 dia. use hair pin. The 1/4 used the duckbill. Some engines used the third type, (which I suspect that you have) the spring lock connection style. Are those retaining clips you mentioned horseshoe shaped, if so, you have the spring lock style. You need a tool to release the garter spring inside the push to connect fuel line fitting to fuel filter. The tool is available at most automotive stores by line size. Safety note, you should release the fuel line pressure before you remove the filter to avoid fuel being sprayed everywhere. I recommend you work on the fuel system when engine cold.
