If one could hook up a hose to the pump inlet, a series of float ball-valves in a rigid tube along the bottom would solve the problem. Think of a long horizontal PVC pipe (but PVC may not be fuel system appropriate) with holes in the top. At each hole would be a floating ball in a small 'cage'. If the fuel level has the pipe submerged, all the balls would float and the entire pipe would be used for fuel pickup. If you turn hard with a low fuel level, any exposed ball-valves would close and seal (ball would seat in the pipe without the fuel for buoyancy) and the pipe would use any open ball valves (portions submerged in fuel) for inflow.
