If the electric pump is in series with the mechanical pump I would temporarily take the electric pump out of the fuel line and see how it does with only the original. You mentioned installing a rotary pump. While the pulse types generally have no issues with pass thru, some rotaries will not allow the mechanical to pull much fuel past them when the pump is off.
