i know they converted a 04-08 on spike tv's TRUCKS show a few years ago but i cant find it on you tube so i found this..

 

Bump. Really interested in this as well.

 

found this bit of info on the LPG conversion also....http://www.granitestatecleancities.n..._and_cents.pdf

 

I did find a few eBay kits for about 600 but they are not EPA approved. They look simple enough to install but it's kinda iffy to me.

 

Chevy and Ram are conning out with CNC trucks. It is about $11,000 more. From what I've gathered is that its not as good miliage, and towing is down. The tanks also seem to take up a good deal of the bed. It can be cheap though to fill up. Some areas can be $1 a gallon equivalent. Also I hear if you have natural gas at home, there is a way to fill up at home, and it gets tacked on to your bill. Might be cheaper now, but as with any supply and demand it will prob creap back up.

 

The 6.2 is the only EPA certified ford engine to run CNG. Westport.com is where to go to look at some info. They are the only CNG company that is with ford in the manufacture of CNG/gas vehicles. Right now it's about 9-11k more than base msrp on either an f250 or 350 depending on which tank size you want. It's mile for mile equivalent to gas on economy according to the ford rep I spoke to.

The fill at home station is good if you don't use much and want to plug it in every night as it takes about 8-10 hours for ~10 gallons. Again according to the rep I spoke to.
