Want to sell this and get it out of the back of my truck. It has the TRAX-II operating system which will refuel the main fuel tank on the fly, don't have to stop to refuel. Has the fuel neck setup for all the OBS Diesel trucks. Aluminum diamond plate box, first picture on the website is what it looks like. Throw some reasonable offers out, thing costs 1700ish brand new. PM offers and we can talk. Want to get my new injectors and need to pay off some other stuff only, but mainly want my stage 1s LOL!
