Anyone know the cost of conversions? I'm looking at converting a 72 chevelle 350 also looking at buying another cng vehicle. Was looking at the ford site at there f250 but they don't come with tanks I'm not spending 40k on a truck and have to buy a $4000 tank on top of it.

I had a conversion done on my 2003 Lexus GX 470. Dropped the spare that had never been used and put 2 steel tanks in that place. My capacity is about 6.3 gge and the tanks are nominal 8.5. My cost was about $8K I think. Mileage is about same as on gasoline. I am happy with the vehicle, too, so it works well for me. My favorite CNG station is the Moore 7-11 where the cost is $.799. That makes my cost of fuel average about $.055 per mile. Little problem with heavy acceleration getting on Interstate and sometimes a lag when it switches over to CNG from gasoline but is not noticeable when you become accustomed.

The 72 chevelle has a carb right? Then you could go with a mixer kit. Alot cheaper than a sequential kit. Easier install also means less money. If your chevelle is orig. you don't have fuel injection so the mixer kit that feeds the carb is the only option. The feeded/fogger kits are not as economical as some of the other kits but they seem to work pretty good.

Read the link

News Ok is doing a much better job in recent months on their overall energy coverage. This is another example.

What's a retrofit run on something like a 2000s model pick up with a v-8 starting to look into buying a truck to retrofit I can't get to my new job without a truck

You may not need a new vehicle to switch to cng tank (http://www.americancng.com/cng-tanks). There are two types of CNG fuel systems available- Dedicated vehicles and Bi-fuel vehicles
