Is a Walbro 255lph Fuel Pump E85 Compatible

I know any exposed metal will corrode from E85, so I wanted to know if my current Walbro 255 is compatible. I know on E85, your injector duty cycle will increase by 20-30%, so I would like to swap to a larger fuel pump or add an inline pump.

Side note: Correct me if I'm wrong, but I realized that the only difference between a Walbro 400lph in-tank and e85 compatible one is that the wires and plug are 'sealed'. If that's the case, they sell that online for $14. The e85 compatible is ~$80 more than the non compatible one. Seems like a worm hole.
