What is this curious looking thing, and what do you use it for?
If you click on the link I provided you'll find out what it is. The picture isn't mine, but those are hard drive magnets attached to the package in the photo. <g>
I believe the fuel line magnets are bogus, but using them on oil filters is a legitimate way to add to the filtering capacity. I also use them on transmission pans and differential covers. Scott.
