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

Quote:
The existing gasoline system is used for cold startup and the system switches to CNG when warm enough for heating the liquid CNG to make it into a gas.
Liquid CNG? Really?

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

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....

Quote:
CNG's volumetric energy density is estimated to be 42% of liquefied natural gas's (because it is not liquefied), and 25% of diesel's.[4]
