CNG and LNG are the same except for storage. LNG is cooled to about -50 degrees to turn it into a liquid state. When it comes out of storage on the truck, it is heated, turned back into a gas then is regulated to the fuel module at 120 psi. The fuel manifold pressure varies from 60 psi down depending on fuel demand. We run about 30 CNG trucks where i work, 12 are dedicated and the rest are dual fuel and 1 bifuel F250. I am a certified fuel system inspector, have been trained in the Cummins/Westgate CNG engines. Sadly, I work on these trucks everyday. Roy
