I'm currently deployed, and I cannot find answers to my questions anywhere else online, so here I am:

I have a 5.4L, but I want to trade my truck in for a 2007 F350 with the V10...

Recently I've been looking into the "E85 concept," and I have learned a lot so far; however, what I don't know is:

1) Does Fords warranty prohibit the use of E85 with its V10 engine?
2) How much of the fuel system is not teflon-lined or steel?
3) Is the fuel tank made out of high-density polyethylene?
4) If any parts of the fuel system are rubber/plastic; are they made of, or do they have: high-density polyethylene, teflon-lining, or tefzel?

v/r,
Phil

 

I can't answer your questions but might I suggest you contact one of the Ford dealers that sponsor this site. Surely they can answer your questions.
