FUEL DELIVERY MODULE AND FLANGE COVER ASSEMBLY - Methods and apparatus are provided for installing a fuel delivery system in a vehicle fuel tank of the type having a sender opening extending through a top of the tank, a flange cover configured to seal the sender opening, and a sender module mounted within the fuel tank. The sender module includes a fuel pump, a fuel inlet fora position sensing algorithm for determining a position of an electro-mechanical actuator (EMA) stroke includes a first rotary component supported for rotation about a first axis, and a second rotary component supported for rotation about a second axis. A first rotary encoder may be configured to generate an output based on an angular position of the first rotary component, and a second rotary encoder may be configured to generate an output based on an angular position of the second rotary component. The first and second rotary components may define a ratio such that the first and second rotary encoders generate unique combinations of outputs for an entire stroke of an EMA. A decoder may be provided having a position sensing algorithm that determines a position of the EMA
