Driggs, I'm a bit confused by your post. I'm assuming it was just a slip that you wrote 'Lower banjo'. Also, you almost make it sounds like you don't use a back-up wrench when you take the fittings off. For the bottom you need a 14 or 17mm (can't remember) open end wrench and then your 10mm flare wrench (again, I think 10mm). You use the open end bigger wrench on the large 'nut' that is welded to the bottom of the filter, then use the flare on the flare nut on the fuel line. If you position them close enough together, you can just squeeze the two wrenches towards each other. It's very easy. The hard part comes in if you round the flare nut. Then your life goes to hell. You can do something similar for the top banjo. Again use the larger open end wrench on the filter 'nut' to keep it from rotating. It is generally not effective to rely on the fuel filter bracket to hold the whole thing firm enough to remove the lines. The filter is held on by rubber isolators so the entire assembly is really floppy.
