I don't know what you are doing? Most of the fuel filters Ford uses screw directly into the carb.

Do you have the brand name and part number for these fittings? Or can you post a closeup pic of the fitting?

Are you using the stock fuel filter that threads directly into the carb inlet?

The fuel pump and inlet side of the filter both use inverted flare fittings. This is the type of fitting typically used on brake lines, for example:

I'm not sure of the exact thread size on those fittings, but it's a standard size for a 5/16" line.

I wonder if if you accidentally got fittings with tapered pipe threads instead. The thread dimensions may look similar but they seal in a totally different way.
