Tanks and pump E85 compliant?

OK this is a long shot since there probably aren't a lot of people trying to run E85 on here but its worth a shot. First a backstory, I'm running a turbo charged audi ABZ motor and have sized the injectors for e85 and have installed two pumps inline to supply enough fuel. Here's my question, does anyone know if the factory in-tank pump is e85 friendly or will e85 eat up the seals/plastic that its made of? Everything else I've had to order specifically for E85. I'm trying to get lucky and avoid replacing the pump and my fuel lines (the fuel lines are aluminum so they should be OK (but certainly small)).

The tank, which is plastic should not be an issue; but ALL of the fuel lines will be a problem as in an E85 vehicle these should be stainless steel, which they are not. E85 absorbs water way faster and to higher levels than normal gas, corrosion becomes a major consideration.

The fuel lines seem to be aluminum, are they not?

Check out twist lok fuel lines. E85 compatible, flexible for easy install, AN6 lines have nearly same ID as our stock lines, and the are likely compatible with the fuel rail barb connectors (don't know this for a fact but the twist lok houses are designed to be used without clamps)

I should have heeded this advice loong ago. Too late now... Its hard to make 750hp on pump gas so E85 is my only option I'm afraid.
