Anyone had any leaking issues with the Ryco z373 fuel filter? Fitted a new one today on the fg xr6t. Done up tight and it leaks, threads and lines look good just doesnt seem to seal. The old filter is a Ryco z373 also but its about half a cm smaller in lengh and is steel rather than aluminum. Maybe the aluminum doesn't like being done up too tight? 🤔 Any advice appreciated 🙏
