Just bought a 1999 Dodge cargo van at auction its a CNG only but I figure I will take a few accessories off it and hopefully sell it for a few bucks profit...
only had 37K miles on it...
Thinking I may convert it to gasoline.. not sure what is involved other than a tank, fuel lines pump and prob PCM... Colorado sucks for CNG only one company has stations and you need a fueling card account. I used to have a card for them but lost it long ago after I sold the CNG Crown Vic I had....
But will prob ebay or craigslist it as New Mexico and Utah have cheap CNG...
these vehicles are great in big city areas where u can use car pool lane and lots of fueling stations to choose from.....

Maybe I should use the parts to make a CNG/diesel 7.3 hybrid
I read an interesting article on some research study where they went from 15 to 40 MPG running Diesel/CNG instead of just diesel
I wish there was a better national CNG infrastructure. with no byproducts of combustion the oils stays super clean and very nice on the engines. 25K mile oil changes are nice too

I know a little about CNG but I have a lot of experience with LPG as I ran it in my 76 F-200 (long story on the 200 part) all through high school. I couldn't argue with $0.26 to $0.40 per gallon.

The benefits are many with that stuff though. I wouldn't run CNG as a supplement in a diesel engine though...too much risk with high combustion pressures. Besides, it's far too much of a "fad" or designer drug at the moment.

Friend of mine bought a CNG van for dirt-cheap (surplus airport shuttle, E350, 9-passenger) just so he can drive alone in the car pool lane. Cuts his commute time in half for the cost of only $800 bucks instead of $20K - $40K for a hybrid or electric. Lot safer in traffic than a motorcycle.
