I don't think you would have an issue if you went with Bosch ev14's, not sure about the Siemens.
I recommend the Xspurt 1000's for e85 use, even ID's have apparently had issues with e85 coagulating to jelly, I suspect after mixing with the flow test fluid they use, and warranty returns to the US can be pointless. Guys, make sure you run ID's on petrol first.
