LNG Tank
There are one or two LNG tanks. They are mounted on one or both sides of the truck
with the plumbing components accessible inside the rear of each tank. The LNG fuel
tank is, for simplicity of explanation, designed like a vacuum (Thermos™) bottle
which can withstand pressures up to 230 psi, or whatever maximum pressure is posted
on the manufacturer’s label (see illustration).
