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!

    Well I'm new to the cng group and option. I bought a state wildlife dept truck at auction that is a 5.3 chevy with dual fuel gas and cng. I will have a number of questions along the way. looking forward to learning and getting this vehicle back to prime shape. Right off the batt the questions I have now are (1) do these dual fuel vehicles have a switch that you switch or does it do it on its own? (2) the cng gauge is broken and would like to replace it, what do I need to look for.
    Thanks in advance..

    Welcome to CNGchat!
    What model year is the truck? As it is the 5.3 liter then it was a conversion (Chevy did and does OEM builds on the 6.0 liter since 2012). What is the conversion manufacturer's sticker under the hood say? Most of these had a CNG/Gasoline switch integrated into the CNG fuel gauge...

          Here is the owner's manual, where the fuel selector switch integrated with the fuel level display is described on page 11.
