" I believe Wedge is running 100% E85...so...
A. He's running more fuel
B. I'll bet he's tuned for it
I'm not saying you can't run it...I'm just saying it may be overkill as he's not running that high of a concentration and it may be out performing the rest of the system. Maybe it requires better tuning and the OP is doing that. But I don't really see any indication that the pump isn't operating correctly.
