The dual element water sensing fuel dispenser filter comprises a housing with an open end. An end plate is positioned in the open end. Contained within the housing is a filter element assembly that includes a first filter portion and a second filter portion. The first filter portion is formed from an annular pleated paper filter media comprised of two layers with a water sensing chemical therebetween. Disposed within the pleated paper filter media are a pair of generally concentric perforate cores containing a chemical fill therebetween. The pleated paper filter media will remove particulate matter from the fuel, whether the fuel be gasoline or an alcohol-gasoline blended fuel. The water sensing chemical in the pleated paper filter media will sense and remove water from the gasoline fuel. The chemical fill will sense the phase separation in the alcohol-gasoline blended fuel and will swell and gell to preclude water from passing through the filter.
