Depends on if he has other restrictions in his fuel system too though.

You need to have upgraded lines, rail, AFPR etc and get rid of all restrictions that cause excessive fuel pressure. If you can keep the fuel pressure as low as possible the pumps will flow quite a bit more.

I am not saying one way or the other, you might be right that he needs bigger pumps, but i just don't know either setup enough.

I personally wouldn't run dw300's in anything, they haven't shown to do dick over a relief modded wally 255. I'd run twin 450's if you need that much fuel, or man up and do a full setup using a big ass weldon.
