I got my grandfather's 1956 Buick running again a few years ago and he originally had a LuberFiner model 200s bypass filtration system installed. Unfortunately these units are very obsolete, but I have been considering running an old AC Delco or Fram bypass system from the era. Filters are readily available but the stacked disc media are all but obsolete as well. As far as I know, the replacement filters are just standard filter media and nominal micron rating is sketchy information at best (one source says 10 nominal and another says 32). Has anyone converted a system like this to accept a role of toilet paper? I know Frantz used to make conversions for these canisters as well, but they're pretty hard to find compared to their normal Frantz filter counterparts. Suggestions are also welcome. I have a large 5 micron nominal spin on bypass filter, but I'd rather keep it period correct.
