Hey gang, CNGchat needs your help!

For over a decade we have enjoyed providing this little corner of the Internet for folks to discuss all things natural gas vehicles. It is the largest forum of its kind: with some 70,000 posts on over 11,000 topics. But with continued low gasoline & diesel prices and strong automaker support for electric vehicles, consumer interest in CNG has dropped considerably, and with it has visitor traffic here. As a result, Google ad revenues no longer cover hosting fees.

If you find CNGchat to be a useful resource then please consider making a modest donation to support keeping this remarkable pool of knowledge available to the alternative fuels community. Thanks!

  • Conversion kits CARB requirements???

    Hey everyone,

    I live in California and I don't know all the legal stuff about the CARB requirements. Is it possible to install a kit yourself or does California require that the conversion be done by a licensed mechanic. Also I keep reading about CARB certified kits.

    Is it possible to build you own kit off of certified components?
    Do the tanks need to be certified or just dot certified?
    Do they sell kits without tanks and I can just pick up used tanks?
    Is the conversion of a Scion Xb possible? Legal problems? Kit problems?

    Any assistance you can provide is appreciated Thank You.

    If you go to the CARB website , and really do some digging ,you can find CARB approved non factory modifications , etc , listed by the product maker.

    IIRC ,the last approved ones were around the 1995-1996 model year time frame.

      So much for "Land of the free, home of the brave"

      So are you brave enough to put a conversion kit on anyway in this free country?

The burden of proof lies with THEM, and they simply won't be able to prove that it's more harmful...

          CARB, however, is a different story. I don't live in CA, so I'm not very familiar with their rules.
          So in other words, your saying that they can't simply see you with your non-EPA cert car at a CNG filling station filling up, and they cannot just cite you and issue you a fine of $10000 like everyone seems to fear will happen? Where does it say that it's not illegal to install a kit? I'm pretty curious to read about that. It's hard to find out about the truth regarding laws in this field, but if it's that easy, then I'd like to get armed with that info as well in case I ever have a run-in with the wrong people.
