Fuel Injection Rail problems of the 2006 Ford Expedition

My customer called to inform me that he was smelling raw fuel inside the vehicle on April 13,2012. I told him it was probably a stuck injector. Being a Ford senior master certified auto repair technician/ase master certified for Ford dealerships for over 14 years I was aware of the injector concerns with these vehicles. I checked the engine oil to find that it was overfilled a quart and smelled of fuel. My diagnosis was correct #2 injector was leaking badly. I replaced #2 injector and changed the oil,found small shards of rust in the injector that could only have come from the fuel rail as they were too large to have by-passed the fuel filter. 2005 f seriesexpeditions/navigators had a recall on injectors and the 2006-2007 vehicles should have had the recall. This could be a potential fire hazzard causing major engine damage if it occurs again. Research online and found that thousands of Ford Expedition,licoln navigator and f-150-250 owners have had the same problems with injectors. I am also aware of a recall that was on certain Expeditions and navigators for a new fuel rail that was rusting internally causing the same problems but the recall just claims that the fuel rails were "defective". Ford motor company is aware of these concerns and refuses to resolve or help any owners of the affected vehicles outside the recall. If these vehicles are allowed to continue to operate without being properly repaired eventually someone is going to be injured or worse. I have witnessed engine explosions and fires caused by leaking injectors. This is clearly a manufacture defect and should be adressed by Ford motor company. I urge any Ford owners with this problem to file a claim with NHTSA as well as Ford motor company so they can resolve these concern before anyone is harmed. All my customer wants is the fuel rail and injectors replaced.
