    Pretty much all newer vehicles use hoses and what not that are e85 compatible to future proof for when ethanol % is upped due to emissions. There's definitely not different hoses and what not from the f150 flex fuel 5.0 to the f150 ecoboost.
    As you said though it burns faster so the issue with the ecoboost is the fuel system keeping up and truck running to lean but running the 3, 4 gallons to 32 gallons of regular fuel is not an issue. Some people do run e30 or more but I keep my blend to roughly under e20, more like e15-18.

    Its done wonders for knock readings.

    Have you been running a 93 tune with this mixture?

    No I personally wouldn't trust it (getting the mix ratio just right) I use it for a safety cushion for my 91 perf tune.
    I know people have though

    Your right as far as the fuel system goes. All newer autos can handle e85 just fine. The problem is the higher the alcohol content the more of it is required to get the same energy out of compared to gas and until we get a new HPFP that can flow what is required for e85, the ecoboost platform has to sit on the side line. We have the lift pumps and now the injectors to handle it, but now the HPFP is lacking.

    As as fas as alchohol burning faster than gas, it actually burns slower than gas. Which is why you can run more timing on heigher alcohol blends. It ups the octane rating which is why you see less spark knock.

    I think what he meant is, you need more fuel volume, hence you go through it faster.

    Stock I can run a 15% blend. Tuned for E30 now, and with no issues to speak of besides the EBOV not cooperating occasionally. I still manage 16-18mpg when I'm not stop-light racing.
