The reason EFI users draw fuel from the bottom of the tank is, there's no suitable place on top of the tank, unless you're willing to modify your tank. The one possible alternative is to draw from the OEM pickup tube and return through a fitting in the filler neck. Ufo-low's tank has either been modified or it's a very unique one-off factory tank. Either way, drawing from the top is always more desirable than the drain plug option, from a safety perspective.
