My primary filter is MB 000 184 57 25, so we may be speaking the same language. The bypass filter dumps to the pan, the primary to the block. I use a Baldwin P40 for the bypass filter, and simply wash the primary. Bolt and a couple of washers to seal the ends, slosh around in fuel (wear gloves unless you want hands like mine), let air dry overnight, then look for tears. The ends are different diameters, so install it right or it won't work. I think the big end down, or the words up. Most of the time I take a peek at the mount. Also brazed a nut at the bottom corner of the can. Short bolt and a copper washer means I can drain the can before removing it. Today a TIG welder would work just as well as brazing. Get the nut on before drilling the hole.
