I needed something to help me marinate my brain in this, so i made a 1/2 scale model out of pattern board and 2" tape. the chrysler pump module will set in the center of the very top section [fwd] -It's 18 gallons now, up from 15. this is the last major modification needed before the wiring can begin. I might have 500+ miles of range with this. that's a lot.
