I don't think the thing IS a filter..... I think they guy was just comparing it to a filter sock like is used on most in-tank pumps nowadays...... He was not a Holley rep, just someone that was going through the show and thought it was a slick idea. I like the looks of it. One application I could see that it would be nice in..... would be hard to adapt, but on my IH Cub Cadets, they are a bottom tapped, gravity feed gas tank. So that is the issue I see in making it work. But, the tank pickup is on the far left side of the tank, centered front to back, on the left edge. If you have the tractor off-camber toward the right, where the right side is "lower" than the left side, like if you are plowing soil, or mowing a hillside or ditch, you can run out of gas, because all the liquid runs to the downhill side of the tank..... something like this would be really nice to keep the engine fed, no matter the angle of the tractor. I could see it be really nice in a boat also...... since the fuel is all over the inside of that tank as you are bouncing across the water......
