Flex-Fuel Module
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The flex-fuel module is a DC-AC-DC converter. It acts as an interface between the fuel pump module and the instrument cluster fuel gauge. The flex-fuel module is located in the instrument panel, on the right side of the steering column, just behind the integrated control panel (ICP).
