Radium fuel basket is a slightly larger area within the pump and still relies on a 1-way check valve to fill the basket, but either system will still encounter fuel starve issues depending on slosh.

The positive aspect of the Radium offering is it can take a return line from a return-type fuel system to fill the basket as priority, so unless you're going with a surge tank offering IMO it would work better than the Verus Flapper, but you'll still run into issues.
