My truck has been running on LPG for many many years. My grandfather bought the truck new in 79' and its pretty much ran LPG its entire life. It does have the gas system on it which was readily available until about 8 years ago. I might go ahead and pull the gas portion off entirely but am thinking of having it as a backup option. Couldnt tell you fuel mileage or anything like that due to being away from it for a long time. She should be home in come thanksgiving though...

I know its a mess under the hood as i havent started cleaning it up just yet.
