A friend of mine sent me a link to an ad today, that is like many others I've seen over the last couple years. The ad is for a "Fuel Filter" for a car or motorcycle, and features a removable set of baffles with a straight hole bored through the center. These units also feature 1/2-28 threading, something I've never seen on a single automobile of any type, and no real filter screening whatsoever. I suspect the design is terrible for liquid filtration, however I suspect it may have an effect as a sound suppressing device.

Anybody else see these ads? Curious if I'm just crazy and this is actually a filter of some sort, or this is a blatant attempt to circumvent ATF regulations.

Thoughts?
