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!

    Have not run the CNG in several years. Out of nowhere - - the control box under the dash is screaming at me every time I turn the key on.
    Where do I disconnect this monster ?? I have no diagrams/documents on the system. Bought the truck as is in 2001.

    I just bought a 1995 F150 4.9L E4OD 3.55 rear-end with 103K miles on it. It has the 021001009 CNG system minus the expired tanks. From what I have read we have unicorns. Following this thread just for educational purposes. I plan on getting the 2 tanks replaced.
