DudaDiesel Alternative Energy has them on Ebay..

4 Cylinder CNG Natural Gas Conversion Kit for Gasoline Fuel Injected Vehicles | eBay

But, they aren't cheap.. :eek:

Interesting product.. Now that gasoline is getting to be a bit steep.. :mad:

Be wary, this statement on the listing is not true:

Liquid CNG? Really?

And this "kit" does not include a tank. No mention of operating pressure either.

What's not true about it ?

Evaporating a cooled liquified gas will take some heat input as the evaporation process draws considerable heat from its surroundings - freezing any water in the air.

CNG = Compressed Natural Gas. It's not liquid in the tank, where in the injection process do you think it becomes liquid?

Never. Especially since there is no tank or regulator included, there is no way to run LNG (Liquified Natural Gas), and you need cryogenics to install it.

BTW, most CNG applications are about 3000 psi. This is not your backyard BBQ propane tank we are talking about. From wiki....

BBQ anyone? :)
