Ethanol fuel may be causing flapper valves on
Ford vehicles to stick. A consumer auto-help
column recently took on a question from an owner of a 1998
Mercury Mystique GS who was having problems filling up his tank. The responding technician said Ford sent out a technical service bulletin that suggested replacing flapper valve assembly. Apparently the flapper valve can stick due to swelling and distorting "when exposed to
ethanol fuels." Let this be a lesson to those who think that an
ethanol conversion is as simple as adding an auxiliary
ECU controller that instructs the engine to pump more fuel because ethanol doesn't pack as much energy.
