Making your own E85?

[Vicious95Z28]

So how are you guys plumbing the twin pumps? Seems like even with twin 255's the line size would need to be increased to take advantage of the additional volume. Is there an aftermarket twin pump module for down in the tank or are you guys putting a sump in the bottom of the tank and running inline pumps?
If I supercharge the engine I'd like to use an F1 and shoot for the 700rwhp mark. What are you guys thinking?
