Since I don't really have time to install these anymore I'd figure I'd still make them and sell them on eBay including an efie from www.fuelsaver-mpg.com or map sensor enhancer if a diesel. Plus all the wiring, relays, switches, plumbing and reservoir. It's an 8" x 8" 29 plate dry cell, -6N+6N-6N+6N-. The plates are 316L 20 gauge, plexiglass at the ends with 3 1/4" bolts on each side squeazing everything together, 1/8" gaskets I made myself. I was thinking of selling the whole thing for $400
