    Cowboy,

    So, let me understand your logic. It is not safe to overpressure your tank, but since (you say) that someone will, we should help them do it. Is that what you are thinking? That is like saying, "It is not safe to run red lights, but since someone will do it (even if its one time - like in an emergency, right RiversideCivicGX?) we will say it is okay to run red lights."

    We don't want anybody talking about making an adapter. It is illegal and unsafe. If you want to fill using the 3600 psi pumps, then get a 3600 psi rated tank.

    Does anyone know a shop in the Los Angeles area that will convert a 3000 psi system on a crown vic to 3600? Closest one I've been able to find that advertises this is in Phoenix - in addition to being really far, I wouldn't be able to make it between the station in Indio and the next one in Phoenix with my current range. Tanks are expiring soon anyway, so was thinking if I'm going to spend the money for replacement tanks, etc might as well get the extra range.

    Any help greatly appreciated!

    Wasn't sure, thats why I posted as a question. Thought most systems would detect an overload, if not good to know

    What sensors? I have never heard of sensors triggering an error light on a CNG system because of pressure.

    Here's the short answer. The same size 3600 tanks hold 20% more fuel when full than a 3000 tank. That's the only difference. Just as safe.

    3600 systems can be filled from either nozzle. The 3600 nozzle won't fit on a 3000 system.

    Different design pressures. The 3000 psi tank is only unsafe if operated above 3000 psi. I would assume that the shell thickness and the hoop wrap could be thinner on a 3000 psi tank and therefore lighter. If it is used on a 3000 psi system no problem. If added to a 3600 psi system, then the vehicle could only be safely filled to 3000 psi. Somebody on this fourm who is a whole lot smarter then me can correct me but I think in the past all CNG vehicles were limited to 3000 psi. Later on, the U.S. raised the allowable pressure to 3600 psi to allow more fuel to be stored in a tank of the same physical size. I am not sure if Canada now allows 3600 psi or not, but at one time the standards were different with each Country. Pressures will rise with the advent of Hydrogen fuel. The Honda Clairty operates at 5000 psi and some are advocating going to 10,000 psi to get some range out of Hydrogen fueled vehicles.

    started a topic 3000 psi VS 3600 psi???

    3000 psi VS 3600 psi???

    Can anyone explain what is the practical difference between tanks labeled 3000 psi and 3600 psi?

    Is the 3000 psi an unsafe tank?
    Thanks
