thanks, yep I checked with Aeromotive and they said fine with E85. The technical spec's that come with the pumps also says that they're ok with Alcohol, they're then rated for less power as you need more fuel to deliver the same power -hence 2 pumps to be safe.
Pump #1 runs via the speed controller and Pump #2 will be rpm/boost referenced via the ECU when we get that sorted.

looks like stainless will be the go for inspection /pump covers. thanks for your help!!
