For what it's worth, the outlet valve in the fuel pump is essentially a check valve. A diaphragm pump won't work without it.

Close Johnny,

Both the Inlet and the Outlet valves have to be check valves, so both would have to leaks to let the fuel run back.
But, if you sucked up rust from the tanks, I suppose it could happen.
