NFPA 52 is a "Vehicular Fuel System Code". The CNG diamond is required unde the code. NFPA 52 does not have force of law in every state. However, it is a safety issue since it lets emergy responders know that the vehicle is carrying CNG.

Because I have a fixed LPG tank in my truck and I have a Propane diamond on the lower right rear.

Please do everyone a favor and put the diamond ont the vehicle.

Also, as per NFPA-52, there should be a sticker near the filler saying 'CNG', and also show the pressure in psi of the system '3000 psi' or '3600 psi'.

There should also be a sticker on the rocker panel in line with the under-car manual shutoff valve that says 'Manual Shutoff Valve'

There should also be a sticker under the hood that says who made the kit, who installed it, when the tank needs to be inspected again, and some other details.

There also needs to be a valid sticker on the tank / cylinder that shows when the tank expires and some other details.

And of course (as stated above by the previous poster), the diamond that says 'CNG' above the rear bumper (not on the rear bumper), on the right rear corner above the bumper. It has to be blue with a grey or white backround, and they had some color specs for the other stickers as well if I remember right

Re: Basic Question ??

The blue diamond should be on the lower right, back in the old days, on a non-removable panel. Somewhere on the lower right should work.
