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!

  • High pressure switch sticking open.

    5 cycles after rearranging my coalescing filter, priority valve and high pressure cut off switch my switch started sticking open???
    It had always been oriented with the gas inlet at the bottom and the gas inlet is now at the top.
    Does anyone know if pressure switches proper operation depends on orientation?
    I suspect the sticking open after inverting mine is not coincidence.

    Is the pressure switch now in an area that is prone to moisture from the coalescing filter? If it is, that is a sure possibility for problems.

      Interesting thought on moisture.
      The coalescing filter traps more oil than water as my gas is apparently quite dry.
      It is more likely it is collecting oil.
      In any case I am concluding that a pressure switch should not be oriented in such a way that it can accumulate anything other than gas or air.
      My plan is to reconfigure it so it is above the gas line rather than below it.

      Thanks for the input,
