Sounds pretty good except fuel stabilzers or additives will allow water to pass through.Great idea.

I've had mine for about 15 years, and I'm pretty sure it wasn't marketed as "Mr. Funnel".

It's definitely a good water filter: there are very few times that some water—and sometimes, a lot of water—isn't filtered out by the trap in the middle. I'd suggest storing these right-side up, so non-filtered debris can't get into the fuel system.
