Ethanol fuel may be causing flapper valves on
vehicles to stick. A consumer auto-help
recently took on a question from an owner of a 1998
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
." Let this be a lesson to those who think that an
conversion is as simple as adding an auxiliary
controller that instructs the engine to pump more fuel because ethanol doesn't pack as much energy.
