Don't like the Daytona fuel inlets.
Goofy so-called improvement.

…which isn't actually theirs. It's their name on what Tomco used to call their "Duro-7" inlet valve. Patented in 1962, patents here and here. I find they do make an improvement—a small one, not a huge one—over the OE pointy-rubber-tip type of inlet.
