E85 with Mechanical Fuel Pump

I calculated 550hp on e85 and got 61.6 gph Using bsfc averages for fuel.
Gasoline .45 - .50
E85 .63 - .70
Methanol .90 - 1.0
I used .70
In my opinion you’re cutting it too close for comfort. You’ll be pulling fuel a long ways through a filter and those pumps are rated at free flow. Any idea what the flow rate is at 7psi? And no way in hell I’d try to do it through a 1/4” outlet.
