"Has anyone here installed a NG/Diesel dual fuel unit yet? Big bucks!!!" There is such an animale???? $$$$$$ I imagine so........
My thinking on it is totally seperate deisel, or LP/NG dual fuel."
There is such a unit. It is called Bi-Fuel technology. It injects NG into the intake. If there is no NG the diesel just runs as normal on diesel. My deisel mechanic has suggested this to us to extend a tank of deisel and reduce costs. http://www.gti-aci.com/
