Can anyone tell me the difference between the fuel system in the 2011 5.0 vs the fuel system in the new flex fuel F150 w/ the 5.0 in it, or any of the Ford vehicals that E85 can be run in. Im not so worried about the injectors, Im looking more for info along the lines of difference in actual fuel lines, O-rings, fuel pump differences, things that would corrode or get eaten up from the ethanol in the E85 over time... if any? When you just do a search online everyone (which isnt very credible I wouldnt think) seems to just say that the fuel systems in new cars CAN handle the ethanol simply because of the ethanol in gasoline. I would think that there is more then the reason of the ECU not being calibrated for it.. but what else if anything would make a difference?
