Best fuel pump to run?

There is only one pump. Some refer to it as the 267 (model number), others refer to it as the 416 lph pump. They are the same thing. I am pointing this out so you don't get confused when reading discussions about it.
This pump is certified for both gasoline and E85. When given the benefit of heavy gauge (e.g. 8) wiring that satisfies its high current draw, a single -267 in-tank pump is good for 600+whp with E85 - more than you need.
What you need to determine (if you've not already done so), is if your EVO VI shares the same pump hanger assembly and wiring pigtail as the EVO VIII-IX. The answer to this question will clarify your options.

You have a few options.
You can go with a turnkey kit such as this one:
http://www.maperformance.com/the-map...el-system.html
I have no feedback on this particular pump or if it works as claimed. This must be used with the optional hardwire kit to get enough electrical power for 550whp worth of E85.
You can also buy the pump/wiring/installation kit individually. You can do it yourself, or some vendors like this one offer a hanger installation service:
http://www.maperformance.com/ti-auto...f90000267.html
One thing to keep in mind is that increasing the fuel feed capacity does nothing to increase capacity of your skinny fuel return line. When a big pump is feeding a load of fuel at idle, a great deal of fuel must be shunted via the return line back to the tank. This creates a bottleneck for the factory return line, which causes the fuel pressure to remain uncontrollably high at idle. This will be an issue for you. Again, there are a couple of options to address it...
One involves retaining the factory high/low voltage pump circuit, which runs the pump slowly at low speeds:
https://www.evolutionm.net/forums/ev...e-circuit.html
Another involves hardwiring the pump, and upgrading the factory return line to an AN -6. And of course, upgrading the factory feed line to an AN -6 while you're in there is also wise and significantly improves capacity on the feed side by decreasing friction losses.
And in either case, you will want to carefully modify the fuel return siphon while you have the fuel hanger out:

So as you can see, the general strategy for using E85 and getting enough for 500+whp is simple, but the small-sized factory fuel system makes it a bit more involved than it seems on paper.

The install kit seals the internal connections, which is a good idea with E85. The Deatschwerks hardwire kit provides more power to the pump. AN -6 fuel lines are not part of this package, and would need to be installed separately.
I advise you take some time to read this discussion:
https://www.evolutionm.net/forums/ev...evo-8-9-a.html
Pay particular attention to the job evodan2004 did by installing the pump and AN fuel line fittings on his factory hanger. He may be willing to do this for you, which will make things much easier.

1 - Summit Racing.
2 - An Fittings Direct
I have a list around here somewhere of all the fittings needed to connect to the factory hanger and an aftermarket fuel rail and regulator.
