Squash is great stuff. Owner always comes to G.O.N.E. (G8 Owners National Event), as he lives in the midwest. Lots of G8's that are blown or turbo'd run his pumps. They are return type.
With this setup for your Flex, I would think that it's a given that they can supply variations for anyone needing more fuel to the engine area. Let's hope that a bigger DI pump and larger injectors are in the pipeline from some source.
