I was interested in purchasing a new FTC. On the Ford site, the 2.5L I-VCT I-4 Gas Engine, says it comes with the CNG/LPG Engine Prep Package. Does this mean the car only runs on either CNG/LPG or regular gas? I read someplace it's just a kit, and a tank would have to be installed aftermarket? So assuming it does both, I would assume it has two separate tanks. How many gallons does it hold? Where is it? Do you just flick a switch to toggle between the two?
I called two dealerships and they had no idea what I was talking about.
