Actually ended up ordering the parts that goingnowhere suggested purely through luck and research(i kind of forgot about this thread). So I have a ms3 being built, FF640 injectors, and a flex fuel sensor. My question is about fuel pumps. I see that the dw200 was suggested. Is that overkill for my application? Is there any downside to getting a pump that flows too much? Any help would be appreciated. I realize I probably can't use the stock pump, but would a 190lph be better for my setup than a 255lph?
I selected the DW200 for my application because they are cheap, reliable, easy to install (plug and play) and they are fully E85 capable. I don't think it's overkill. I would stick with the DW200.

I don't see any need to buy a fuel pump, the stock pump with those injectors is more than enough for your application.

Do you have experience doing so? Or any evidence that the stock pump will survive in e85?

I've run all E85 on the stock pump for the last 2 years and 16k miles with no issues. Granted I'm n/a with bolt-ons.

Well, I got a good deal on a Grams 255 so I'm going with that. I'd rather be safe with a pump i know has enough capacity and is e85 compatible.

Personal experience & knowledge that EPDM doesn't care about ethanol any more than it does gasoline.
