E85 fuel on 2005 E500 (W211) with 5.0L (M113) engine

good morning everyone I was wondering if anybody knew whether I can or cannot run 85 on the stock, fuel pump, fuel line and injectors, or do I have to change all of it for E85? I know I have to get a tune for it, but do I need anything else other than that? The car right now is completely stuck with a intake and a muffler delete thank you very much.

AFAIK, Mercedes does not support use of fuel with more than 10% ethanol. They may not warranty fuel issues if fuel with more than 10% ethanol was use in the car.

You'd have to change a lot of things to run E85, and then you'd need to find a shop capable of reprogramming the ECU to run on E85 - I have no idea if anyone will do this for the Bosch ME 2.0 ECU's. There's almost zero benefit to this... definitely not worth the expense...

i can tune the car myself, i just was just asking what all i NEED to change to run e85. There in always a benefit to running e85 of a car, boosted or not. Thank you tho.
