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!

  • GFI/Sherwood Manual Override Vent Tool Operating Procedures

    Even when you follow theseGFI solenoid tank valve.jpgSuperior pg2.jpgSuperior pg1.jpg it's still a scary process!

    My 1999 Honda GX has a tank with a shorted out GFI valve so it's stuck closed. The GFI valve on my car has (2) 7/8" hex head valve bodies built into it. I'm trying to figure out which valve body to remove from the solenoid valve to install the override tool. I'd never choose a GFI valve if I were building my own CNG vehicle.

      It's a pain and not to be taken on by the faint of heart. Once you start venting there is no stopping the valve gets iced up and you cant shut it off.
