i know im new here, but not new to making hp. i have always ran domestic cars. both of my car i built i have ran e85. Maybe someone could contact a domestic vendor and maybe we could get them to look at building a billet hat for a larger singe, or dual pump set up. here is a link to the guys doing a lot for the ford/ls guys with nice plug and play setups.
i have no idea if they would be willing to get into something like this, but they make nice drop in, plug and play fuel hats and direct upgraded wiring harness for the high amp draws of larger pumps.
