As a shop owner interested in doing CNG conversions this is the latest information from the state on conversions.
1. Installer must have certified as a CNG installer thru the EPA testing requirements
2. Installer must also be a certified Tank inspector by the EPA testing requirements
3. You must use EPA certified kits on all conversions
4. 1996 and up vehicles must be OBD2 compliant on both fuels and pass the OBD2 emissions test thru the OBD2 port
5. 1995 and older vehicles must be compliant on both fuels during a dyno test
6. They are trying to set up a certification class for shop owners but it will not happen until about March of 2009 and is being put on by the University of West Virginia.
I have contacted conversion kit suppliers and there is a lot of kits being sold that are coming with USED scuba tanks from China and Japan that have had the fittings installed in them , they are NOT certified tanks and will not hold the pressures that are needed to run CNG -
Current Certified tanks are made by Lincoln Composite and Dynatech
All tanks must be equipped with an on / off valve and you must find out if the tanks include brackets also
According to the manufacturer of the CNG kit the power loss is approximately 20-30%
The cost when they do fleet conversions is approximately $10-15K per vehicle for a complete conversion and you usually need multiple tanks for an installation to give you enough range to make the vehicle ready for practical use.
Turn Key systems cost $5-7K per vehicle plus tanks
