Here's the custom twin fuel pump setup in the stock fuel tank.
It's a pair of F90000267 Walbro E85 fuel pumps, on a custom hanger, with a custom enlarged opening on top of the stock fuel tank. There's a -6 return line, and twin -6 fuel feed lines merging into the existing single -8 line that goes to the fuel rail via a Speedflow fuel filter. The entire fuel system uses braided Teflon fuel lines.
Yes these pumps combined will provide way more fuel flow than I need without a bigger turbo, but I'm not comfortable with how close I am to the limit of one of these pumps, and these are the only ones I trust on E85.
