cng/diesel injection
Had anyone heard of this?
With the fuel prices going so high , I decided to do this to my 81 300SD.
It now has 2 cng fuel tanks in the trunk and runs a mixture. Certainly more power and much much cheaper to drive.
The website I found it at was ewsews.com If you are mechanically inclined, you can do this youself. As for tanks, don't buy a new tank, look on Craiglist or ebay,.

To some or a large extent it might be better to convert a diesel motor. They have higher compression, so they are better able to take advantage of the higher 'octane' rating of Propane or CNG. I think some turbo anti lag devices flow a bit of propane. Most see a mpg increase, but I don't know if they add in the cost of the propane or not.
There are natural gas engines 'converted' or redesigned to run on propane or NG. They do have spark plugs for ignition.
