E85 Question

Is there any truth to the latter and if so would a custom E85 tune from PHP be enough to allow a non-flexfuel f150 to run E85 safely?

Just curious in case gas prices get out of hand and E85 somehow remains low.

Jeff, I have the same question as you. I have a '07 F150 5.4L. I've talked with the tech's at my local Ford dealer and multiple people have told me that all of the parts used in my truck, in relation to the fuel system, are the same as the E85 flex fuel version of my truck... the fuel lines, tank, pump, filters, injectors, ect.... They said that the only difference is a sensor to tell the PCM the fuel type in the tank and the PCM program itself. I think it would be a nice feature to have a tune sitting in my Gryphon that I could load into my PCM and use E85 if need be. Maybe Bill could elaborate on this for us a bit, I trust his opinion more than hearsay on the internet or chatting with the Ford tech's at the shop bay door....
